HIBRIS Highly integrated broadband imaging spectrometer
The Highly Integrated Broadband Imaging Spectrometer (HIBRIS) provides simultaneous global thermal characterization and detailed imagery in the near infrared bands from space. The main purpose of HIBRIS is to take detailed hyperspectral surveys in the near-infrared range, and contextualize them by placing them in a global thermal infrared map. This makes HIBRIS a suitable instrument for earth observation and planetary surveys and characterization from space.
HIBRIS combines the following technologies into one instrument:
- Near Infrared Hyperspectral Imager (HSI) consisting of a cooled HgCdTe detector coupled with a Linear Variable Filter Array.
- Stirling Cycle Micro-cooler that cools the HSI to 80 K providing 400 mW of cooling power. The micro-cooler is positioned to eliminate unwanted vibrations.
- Sapphire Beam Splitter which is implemented at the branch in the shared imaging optics. This enables HIBRIS to operate both a near and thermal IR detector.
- Rotating Input Mirror that can calibrate the micro-bolometer on the fly from up to two sources using a space qualified low power motor.
Using cosine’s Highly Integrated Payload Suite (HIPS) technology for integration and miniaturisation, the volume, mass and power requirements are significantly reduced.
