Thermal Infrared Imaging for Long-Range Surveillance Detection ...

All objects warmer than absolute zero (-273°C/-459°F) emit infrared radiation in the MWIR and LWIR wavelengths (3µm–14µm) in an amount proportional to the temperature of the object. Thermal imaging focuses and detects this radiation, then translates the temperature variations into a greyscale image, using brighter and darker shades of grey to represent hotter and cooler temperatures, which gives a …

Improvement Technology for Far Infrared Sensors - Panasonic

16/04/2021· By introducing this technology to a thermal-type far infrared sensor, heat loss from the infrared-receiving section was reduced approximately to 1/10 of the initial sensor without the phononic crystal structure. As a result, infrared detection sensitivity was improved nearly by a factor of 10 in the sensors with phononic crystals. Panasonic presented this world's first research result on phononic far …
