In this type of sensor, the signal is read out from the pixels in parallel , allowing high speed capture of high resolution images. A sensor typical of Andor cameras is called an "Active Pixel Sensor" - APS. Its operation is as follows:
- Light hits the sensor, an adequate charge is generated.
- The charge is converted into an analog voltage within each pixel
- The analogue voltage is collected successively from each row of pixels
- The analogue voltage is converted into a digital signal in AD converters
- The digital signal is read out at a rate of approximately 200MHz separately for each sensor half
The sCMOS sensor manufacturing technology is based on the design and manufacturing of the previous generation of sensors - CMOS, but compared to CMOS, sCMOS sensors have the following capabilities:
- Extremely low noise
- High sensing speed
- Wide dynamic range
- High QE
- High resolution
- Large field of view
in one frame at a time.
