The linear sensors by Fairchild Imaging are used in many high end applications for industrial quality control.

Sensors with antiblooming circuit special structures on the chip avoid that a bright region of the optical image causes the readout register to saturate and to distort the recorded signal. Exposure control allows integration times below the line frequency of the sensor, which is essential e.g for imaging quickly moving objects. CDS ( CDS = Correlated Double Sampling) finally is a technology which increases the signal-to-noise ratio of the sensor.

CMOS linear sensor

Fairchild Imaging offers also a linear sensor based on the ‘’ Active Rest Technonology’’ ™ by Agilient Techonologies.This sensor provides highest sensitivity, a very low dark noise and a pixel frequency of up to 80Mhz via two outputs.

TDI linear sensors

"TDI" (Time Delayed Intgration) means a technology, in which the charge packages in the sensor are moved internally across the image plane synchronously with the object to be scanned (comparable to the vertical shift register of an area sensor). Therefore, despite of the movement of the object, always the same part of object is always scanned, multiplyingso the integration time is multiplied by the number of TDI stages.
For this reason, TDI sensors offer advantages compared to standard linear sensors. Beside a reduction of the noise, above all, the a higher sensitivity is to be mentioned.This iscan be an advantage forat applications with quickly fast moving objects, if the exposition times are too short for normal linear sensors.

CCD area sensors

CCD sensors by Fairchild Imaging are often used in aerospace mission (i.e : Mars Observer, Cassini probe, Hubble Space Telescope) and many reconnaissance satellites. For such missions the sensors can be specially tested.

Lot of sensors area available from on stock as well as ‘’frontside’’ or ‘’backside-illuminated’’ version. For many other sensors this feature can be specially is available on requested.’’Backsied-illumination’’ is a way to increase the sensitivity of CCD sensors. Here the substrate of the sensor is grounded down to a minimum and the sensor gets mounted into the housing upside down. So the usually disturbing gate-structures are now on the under surface. This high operating expense is profitable because of the immense increase of the sensitivity of the sensors.
