Photon Counting Cameras
“Photon Counting” applications require an image sensor in which the arrival of a photon at a pixel can be sensed with a read noise of < 0.3e- . Gigajot’s Quanta Image Sensors (QIS) achieve an industry-leading 0.19e- and 0.27erms read noise, while operating at full resolution and high frame rate without the use of electron-multiplication.
Gigajot’s proprietary low-noise cluster-parallel readout technology achieves reliable photon-counting sensitivity at room temperature. Gigajot’s patented pixel design and architecture also results in an unprecedently low dark current at room temperature. The sensor utilizes in-pixel dual-gain readout to achieve a single-exposure dynamic range of 100dB and has an 12-bit ADC resolution.
Gigajot’s QIS cameras interface to a user’s PC via a USB 3.0 SuperSpeed interface. The user-friendly GUI software that is provided with these cameras enables control of the sensor, image/video capture, real-time processing, and analysis.
