WORKSHOP PAPER
Wide Dynamic Range Low Light Level CMOS Image Sensor
Abstract
This paper describes a CMOS image sensor technology suitable for the next generation of scientific cameras. We describe a prototype sensor with 320x240 pixels based on this technology. The sensor features 8 different types of 5T pixels with pinned photodiodes. The measured peak quantum efficiency of the sensor is greater than 50% at 550nm, and the read noise is less than 1e- RMS at room temperature. The sensor also achieves an intra-scene linear dynamic range of greater than 92dB (40000:1) at room temperature.Keywords
