Caeleste Publishes its IISW 2015 Papers On-Line

Caeleste puts its IISW 2015 papers on-line:

1. "CMOS image sensor reaching 0.34 eRMS read noise by inversion-accumulation cycling"
Qiang Yao, Bart Dierickx, Benoit Dupont, Gerlinde Ruttens

Record for lowest read noise in CIS. CMOS pixels is pushed a little bit further again, as reported in our 3rd IISW paper. The value of 0.34 (sic) electrons RMS is obtained at the cost of accumulation-inversion cycling, severe oversampling and cooling down to -40°C.

2. "Four Concepts for Synchronous, PSN limited, true CDS, HDR imaging"
A.K.Kalgi, B.Dierickx, B.Dupont, P.Coppejans, P.Gao, B.Spinnewyn, B.Luyssaert, A. Defernez, J. Zhu, J.Basteleus, Q. Yao, W. Verbruggen, D. Uwaerts, B. Uwaerts, G. Ruttens, G. Cai

Comparing 4 HDR methods. Here we use a pretty strict definition of “High Dynamic Range”: It must at the same time comply with: 1) knee-less fully linear 2) allowing RWI synchronous shutter and 3) complete CDS. 3 methods are actually Caeleste patents, the 4th is the historical “overflow barrier” method.

3. "Imaging sparse events at high speed"
Gaozhan Cai, Bart Dierickx, Bert Luyssaert, Nick Witvrouwen, Gerlinde Ruttens

Ultra-high speed readout of a sparse image. The first imager to realize ultra-high speed sparse readout of a megapixel small-pixel (8µm) array, by copying a “SLICE” of the pixel array data into a processor array. The below 1Mpixel prototype is able to output about 8000 frames per second.
