A Noise-Equivalent Temperature Difference (NETD) as low as 23 mK was measured with INO’s IRL512 FPA in a radiometric package:
- Broadband filter centers in the 8-12 µm wavelength band
- 140 ms integration time
- f/1 optics
- Characterization in flood exposure
The radiometric package successfully passed the following environmental tests:
- Thermally cycled from -55 to +85°C according to MIL-STD-810
- Randomly accelerated up to 14G RMS from 20-2000 Hz
- Shock tested up to 75 G
The package also shows a very low sensitivity to stray radiation due to a specially designed, high-efficiency radiation shield.
Under the Space Technology Development Program of the Canadian Space Agency (CSA), INO has designed, assembled and radiometrically characterized a radiometric package for its 512x3 pixel microbolometer FPA. The design of the radiometric package was based on INO’s FPA, allowing the development of a small, low weight, low power consumption sensitive detector package ideally suited for infrared pushbroom imaging applications.
