Abstract

Acousto-optic signal processing systems require linear detectors arrays with wide dynamic range and fast transient response. In the past, these two characteristics have not successfully been combined into a single integrated detector array with a large number of elements. DALSA's DYNASENSOR detector utilizes an optimized, ion implant doped, profiled MOSFET photodetector specifically designed for wide dynamic range. This detector, originally introduced by DALSA over a year ago, has been redesigned to improve transient response. The new device offers high speed, linear response characteristics at low light levels or short integration times (on the order of 1 microsecond). To achieve the short integration times necessary in acousto-optic applications, the DYNASENSOR has been implemented in a tapped array architecture with eight outputs and 256 photoelements. Operation of each output at 20 MHz yields detector integration times of 1.6 micro-seconds.
