No other uncooled array can provide this combination of performance and features, even when more complex interfaces such as time delay integration are considered.
A custom product, from design to fabrication
The reputation and experience INO has acquired over the years with the IRL256B and RIM160A convinced the European Space Agency and Canadian Space Agency to jointly finance the project. From the drawing board to production of the end product, our team of designers and researchers delivered an entirely custom product. The results: a linear array that consists of three parallel lines of 512 pixels on a 39 µm pitch. Each pixel includes both active and reference detectors to reduce pixel-to-pixel offset variation, eliminate common mode bias noise, and increase the circuit’s immunity to die temperature drift. The thin films making up the active detector structure are designed to provide high and uniform infrared absorption between 8.3 and 13 µm. The pixels are fabricated monolithically over a custom CMOS readout integrated circuit using a surface micromachined post-processing approach. The circuit integrates the signals of all pixels and provides 14 bit digital output.
Despite the small pixel size, the projected thermal resolution over the 8–12 µm spectral band for f/1 optics is below 50 mK, and below 250 mK for any 1 µm wide spectral band between 8.3 µm and 12.5 µm.
