CMOS Linear Sensor by
FAIRCHILD IMAGING INC. 

FAIRCHILD IMAGING now offers also a linear sensor based on the „Active Reset“-Technology (TM) developed by PDI. This sensor provides highest sensitivity, a very low dark noise and a pixel frequency of up to 80 MHz via two outputs. The sensor is suitable for high speed applications in industrial quality control or other areas of image processing.

94dB dynamic,
85% fill factor
CDS, Anti blooming,
2 outputs



The CMOS1421 can be used in two operation modes. In RDI mode the sensor can be read out while the integration continues. At a readout frequency of 38kHz the readout noise is only approx. 9 electrons. In MRDI mode, which allows a multiple readout during integration, the readout noise drops even below one electron at a line rate of 2.9kHz.

The CMOS1421 is used in the line scan cameras of the OWL series (please refer to page 5). These cameras are available in two different versions and are suitable for the industrial quality control.
