Abstract

This paper discusses the problems of the realistic evaluation of high speed, high performance infrared focal plane arrays. A measurement system has been developed based upon a previously reported flexible, electronic control and correction system. This approach allows focal plane arrays to be tested under operating conditions which are very close to those used in real systems. A number of test modes are available, allowing the operator to focus on particular aspects of the array performance. In addition, particular attention has been given to ensuring that tests can be carried out at realistic operating speeds. Both static and dynamic characteristics may be measured and compared directly with imaging performance. This is especially valuable for some focal plane architectures in which the photovoltaic elements are not directly accessible via external terminals, eg CCD readout. Relatively large numbers of data samples can be acquired from each array and a range of statistical techniques are available to assist in their interpretation. Both spatial and temporal analysis may be applied.
