Interpretation of the 3- to 4-Micron Infrared Spectrum of Mars.
Martian infrared spectra and those of D2O-HDO-H2O mixtures and, particularly, of HDO.
The infrared detector confirmed that there was something in the direction the antenna pointed, but it appeared too small to be the warhead.
The infrared detector showed two targets which the radar insisted weren't there.
The infrared detector gave him no range information, of course.
He switched off the radar, and aimed the ship slightly to one side of the infrared image of the jammer.
The target vanished from the radar, but the infrared detector insisted there was a nebulous fog of hot gas, shot through with a rain of molten droplets, where the target had been.
Cal took the chance that they might have an infrared viewscope directly on him, and he waved his arms above his head.
If after dusk, they still might have spotted them in the infraredviewers which picked up the heat differentials and gave a fair approximation of shapes.
Infrared has come into its own through missile electronics.
Infrared food blanching, for instance, is highly effective in preparing foods for canning or freezing.
The entire infrared field should be significantly assisted in its growth and application through our missile-space programs.
Infrared cameras are used in analyzing metallurgical material processing operations, to aid in accuracy and quality control.
Infrared is being used industrially to measure the compositions of fluids in complex processes of chemical petroleum refining and distilling.
He flicked more switches overhead and the infrared and radar systems came on-line, their displays like Christmas-tree lights briskly illuminating one by one in rows.
Thanks to the goggles, both of them could see the normally invisible beams of the infrared flashlight.
Malone flicked on the infraredflashlight he held in his hand.
Infrared equipment went on again, and the eerie illumination spread over their surroundings.
He hurried after him, using the infrared light because the candle was too far away now to show him the path.
It took him only a moment to find the camera and lift it from its case, then he handed Zircon the special glasses and quickly fitted his infrared telescopic sight onto his own rifle.
He turned off the infrared light, and, leaving a trail of torn cloth behind him, he crawled toward the source of the light.
The beam of the infrared camera didn't penetrate far enough for him to see what or who was under the red light.
He switched off the infrared light, and instantly all light was blotted out.
Rick knelt quickly and put the infrared light on the wound.
The trail he had left showed clearly in the infrared light.
In a few moments there was quiet, and the infrared light found nothing but the silent woods.
Then he carried the unit to the edge of the saucer and pushed the button that lit up the infrared light.
Because when the battery for the infraredlight ran down, there would be nothing but darkness.
The searchlight gave off invisibleinfrared rays instead of ordinary light, and the telescope was equipped with special lenses in order to pick up the infrared.
The infrared camera, placed on the seat with the beam directed ahead of him, gave him plenty of light to see.
When Rick switched on the infrared light for a moment, the incredible scene leaped to his eyes from the darkness.
From under his feet a lake stretched away, its farther shore beyond the eight-hundred-yard range of the infrared light.
With the glasses on, using the infrared light was just like using a powerful searchlight.
Rick now proceeded more cautiously, and he switched off the infrared light in case the Tibetan should look back and possibly spy the glowing filament of the lamp.
I switch the vision to only twenty percent infrared overlay so that I don't have as much information to distract me, and I brace myself.
I switch my eyes to +IR mode so that they overlay theinfrared frequencies of the electromagnetic radiation around me over the top of the human-visible ones.
Back and forth, cross and re-cross, with the infrared sensors scanning three hundreds sixty-degrees around him.
He concentrated his attention on the infrared detector that hung before his viewplate.
He turned slightly inside the suit and tried to judge the iceberg's distance through the infrared detector.
He stared blindly through the useless viewplate in his helmet, then reached up slowly and carefully to place the infrared detector before his eyes.
A black PVC container may work even better than a black-painted jar, since PVC is a good infrared radiator--these matters are still being studied.
HDPE and ordinary polyethylene bags work well, since polyethylene is nearly transparent to infrared radiation, allowing it to escape into the "heat sink" of the dark sky.
The infrared was useless; by it the flickering firelight was blinding.
He tried the infrared viewer, but it showed no more than he could see with the naked eye.
But with the infrared searchlight on him, Rick could see him through the telescope as though it were white light.
Rick crouched down under the dashboard and rechecked his camera, trying out the infrared dynamo and the camera motor.
Yesterday morning the mail brought me a bill for a thousand feet of 16-millimeter infrared motion-picture film.
He knew the theoretical power of the infrared searchlight, but only an actual test would tell whether it gave enough light for the rather slow infrared film emulsion.
Rick had connected the infrared attachment so that a switch was handy under his thumb when his left hand held the camera in position.
His eye found the telescope and he pressed the infrared switch.
And the filament of the infrared searchlight would be visible, too, against the dark background of the marsh.
Rick had thought about asking his father to help him check the infrared spotlight in the lab, but Hartson Brant was preoccupied with a scientific analysis problem, so Rick decided to check his new invention by actual use.
He and Jerry went directly to the boat landing while Rick ran upstairs and picked up his infrared camera, just in case.
He walked ahead of the camera and peered into the infrared searchlight.
White leader ran through the gate, then suddenly, clear as day, there were two ships below, their center sections brightly illuminated and the rest fading out slightly toward what had been the edges of the infrared beam.
He pressed the infrared switch and heard the dynamo whine softly.
Rick was figuring out some changes in the infrared camera attachment on the following Monday when Scotty came into the room.
Daedalus's infrared laser scanners were still tracking the wing of MiG interceptors, now at twenty-two thousand feet and closing.
The infrared cameras showed the sea plunging toward them.
He flipped a switch under his hand and displayed the infrared cameras on his helmet screens, then absently monitored the massive white trucks towing him onto the darkened tarmac.
Nowadays you even had to find ways to mask telltale waste heat expulsion, which always betrayed an unmistakable infrared signature.
Other screens showed the view of the hangar as seen by the video cameras on the landing gear, now switched over from their infrared mode to visible light.
Then he cut back to the infrared cameras and glanced over the tarmac stretching out in front of him.
And we can defeat their infraredby taking her back on the deck, so the engines are masked from their look-down IR.
He switched his helmet screens momentarily to the infrared cameras in the nose and studied the runway.
The liquid crystal panorama inside the helmet immediately flashed, showing the unfriendly radar and infrared interrogations.
Petra," Androv said into his helmet mike, "take VSD to standby and give me infrared laser.
If we went for altitude, we'd show enough infrared signature to make us an easy target during ascent.
But nobody at NSA is authorized to be interested officially in what goes on in Japan, so the oversight committee wouldn't spring for a real analysis, an infrared overlay or anything.
Even if the radar-guided AAM could be confused, Daedalus had no way to defeat infrared homing.
This time theinfrared light operated continuously.
Rick took the front plate from his camera and put the infrared searchlight on its mounting bracket.
Rick tried the infrared light intermittently, but not until they were in about twenty feet of water did the roiled bottom allow its use.
He has a device which projects infrared light, and glasses that allow the wearer to see whatever that light illuminates.
He held it in the beam of infrared light for Zircon to read.
Once across, he swam down the face of the reef, knowing that the trip was hard on Tony, because the underwater world was completely dark to one without light, or glasses with which to see the infrared illumination.
The unit was battery-powered and had a bracket for mounting the infrared light used for night photography.
His thumb compressed the button on the side of the case and the camera started, the infrared light turning on.
He flashed the infrared light, saw that they were still heading properly, and cut it off again.
Then he reconnected his circuits so the new switch would turn on only the infrared light.
The most widely used Landsat color image is called a false-color composite because it reproduces theinfrared band (invisible to the naked eye) as red, the red band as green, and the green band as blue.
