The sensors that Barry Chambers is
using for 30 THz comms testing are relatively low cost Melexis
single pixel IR bolometers.? The 90614 is good enough to detect
the thermal radiation from the Moon and is calibrated for
temperatures from -170 to +380 ¡ãC and compensated for a wide range
of device temperatures.? It has a resolution of 0.02 ¡ãC and could
probably be used to monitor the temperature of an 0603 or 0402
load resistor.? Might need a germanium or similar longwave IR lens
if the load resistor is to small to fill the sensor active area.
Other models have onboard DSP filtering
and multi-zone sensors.? Base models are around ?30 in 1-off.
