Fujitsu develops first 1Mpixel dual-band T2SL infrared sensor
Fujitsu has announced the development of a high-sensitivity and high-resolution infrared sensor to expand monitoring capabilities in the defence and disaster prevention fields. The over 1Mpixel dual-band sensor is claimed to be the first of its kind in the world.
The sensor is a Type-II superlattice (T2SL) infrared sensor, a device that uses alternating thin layers of III-V compound semiconductors (commonly InAs/GaSb or InAs/InAsSb) to detect MWIR and LWIR radiation simultaneously.
The high-sensitivity of the device allows it to clearly capture minute thermal differences of 0.05°C or less, according to Fujitsu, enabling high-precision monitoring day and night.
The newly developed technology has applications spanning a wide range of fields. For example, when applied to optical sensor systems mounted on satellites or aircraft, it can enable early assessment of disaster situations and environmental monitoring.
The technology was developed under contract as part of the 'PROTOTYPE OF WIDE BAND AND HIGH RESPONSIVITY PHOTO-DETECTORS' from Acquisition Technology & Logistics Agency (ATLA), Japan Ministry of defence, to which Fujitsu has completed delivery of the prototype sensor.
