Abstract

The unavailability of a wide dynamic range CCD area array has resulted in the inability to meet many needed wide dynamic range applications. Typically area array image sensors have at best 1000:1 dynamic range. This paper introduces an array, developed by DALSA that uses the companies proprietary VARISENSORTM technology to yield a dynamic range of better than 100,000:1. This paper will discuss the new array. The VARISENSOR utilizes an optimised, ion implant doped, profiled MOSFET photodetector specifically designed for wide dynamic range. The light intensity is logarithmically compressed into small charge packets, easily carried by the CCD shift register. As a result of the logarithmic conversion, optical dynamic ranges of five orders of magnitude are obtained. The area array is configured in an 128 x 128 interline transfer architecture with a 50 gm x 50 gm pitch. Buried channel CCD technology is used for improved noise and charge transfer efficiency. Applications for this array can be found in the area of laser beam profiling and acousto-optic signal processing, among others.
