| Popis: | We have developed a compact infrared camera (CIRC) with an uncooled infrared array detector (microbolometer) for space application. CIRC is the first microbolometer sensor without a calibration function in orbit, like a shutter system or an onboard blackbody. The main objective of the CIRC is the technology demonstration of wildfire detection. Microbolometers are suitable for application in resource-limited sensor systems or small satellites because no cooling systems are required. Another main characteristic of the CIRC is its use of athermal optics. The athermal optics system compensates for defocus occurring owing to temperature changes. The CIRC achieves a small size (approximately 200 mm), light mass (approximately 3 kg), and low electrical power consumption ( 資料番号: PA1410031000 |
