Abstract

The requirement for lower cost infrared systems has led to interest in sensors based on linear pyroelectric array technology. Like all pyroelectric detectors, linear arrays are free from the constraints of temperature control, operating over the full military temperature range with minimal reduction in performance. Since most objects of interest have, or can be arranged to have, movement with respect to the observer, this motion is used to produce a 2-dimensional image rather than an optical scanning mechanism. Here we describe a linear pyroelectric array which is designed to have good thermal sensitivity, low microphony, low power consumption, and to be easy for the system designer to use without taking special measures. We also describe a sensor head system design which makes use of the features of the detector in order to achieve a good thermal sensitivity along with a practical, low cost sensor design.
