Innovations in Metrology with Active Sensor Control on 25 Megapixel Cameras

Posted by Gretchen Alper on Thu, Aug 22, 2013

Metrology system manufacturers are moving to ultra large area scan cameras (such as 25 Megapixel CMOS cameras) to improve accuracy and throughput, but defects in the image can negate the performance enhancements. 

Active Sensor Control (ASC) is used to calibrate the image sensor output for variations in the exposure response from pixel-to-pixel. The image quality is also affected by several external factors such as lighting, optics, temperature, etc.  This is especially so for ultra high-resolution CMOS image sensors and cameras. Through Adimec’s Active Sensor Control (ASC), calibration can be performed easily in the field to compensate for all disturbances, including those due to system configurations or those that may change over time, to ensure there are no artifacts in the resulting image. These in-camera functions allow for a reduction in computations in the frame grabber or CPU of the total imaging system, leading to lower overall system costs. 

In this free white paper, we provide details on imaging system situations when Active Sensor Control can be most beneficial, and how ASC works to give more usable pixels and a better starting image than cameras without ASC.
