"Caeleste was created in December 2006, by a few people around the former CTO of Fillfactory/Cypress. After an organic growth start, Caeleste is now 22 persons large and fast growing with a CAGR of 30-50%. It is specialized in the design and supply of custom specific CMOS Image Sensors (CIS). Caeleste is still 100% owned by its founders.
...In fact, Caeleste has almost the largest CIS design team in Europe, exclusively devoted to customer specific CMOS image sensors."
Some of Caeleste R&D projects:
- Caeleste has the world record in low noise imaging: We have proven a noise limit of 0.34 e-rms; this implies that under low flux conditions (e.g. in astronomy) each and every photon can be counted and that the background is completely black, provided that the dark current is low enough.
- Caeleste has also designed a dual color X-ray imager, which allows a much better discrimination and diagnosis of cancerous tissue than the conventional grey scale images.
- Caeleste has also its own patents for 3D imaging, based on Time of Flight (ToF) operation. This structure allows the almost noise free accumulation of multiple laser pulses to enable accurate distance measurements at long distance or with weak laser sources.
