A back -illuminated full -frame low -noise HDR 8μm, 12Mpixel, 34fps image sensor for industrial, medical and scientific applications
Abstract
The need for a low-noise, high-dynamic range (HDR), high-resolution, back-side illuminated (BSI) sensor with a frame rate level that allows video applications for next-generation X-ray medical, scientific, and industrial equipment has been identified. Such a sensor will allow reductions in the radiation dose received by patients in medical applications and use of the sensor in low-light conditions while increasing the image resolution. It will make possible fluoroscopy and X-ray video in some healthcare and industrial applications where it is not used presently. To this end, a BSI stitched sensor with HDR, 8μm, CDS-capable pixels has been designed. The sensor has 12M pixels and can be readout at a frame rate of 34fps. The sensor is amenable to many other industrial and scientific applications that can benefit from its 1.5 e- (rms) noise level.Keywords
