The frigates were built to a modern stealth design to avoid enemy radar and infrared detection.
Thallium selenide has been used in a bolometer for infrared detection.
Initially used for measuring star light, it was employed for the infrared detection of airplanes in the early stages of World War II.
They mask body heat to avoid infrared detection.
And since they were now less frantic and more alert, we must follow so far behind that infrared detection was of no further use.
His Ph.D. thesis was supervised by Charles Townes and involves the use of nonlinear optical techniques in infrared detection for astronomy.
Aircraft camouflage now had two major threats that it was not able to fully defeat - radar and infrared detection.
The newer models pipe their exhaust along the bottom to cool it before venting it, making the boat even less susceptible to infrared detection.
Some success was made in the infrared detection, but little was accomplished using radio.
Materials used for cooled infrared detection include photodetectors based on a wide range of narrow gap semiconductors including:
