Abstract
A 2-D photon event detector, consisting of a microchannel plate coupled to a resistive anode for position readout, has been used to measure the spatiotemporal correlation of dynamic speckle. In this paper we discuss the implementation of this detector for these measurements and the effect of detector dark count, dead time, spatiotemporal integration, and other inherent biases. Initial results on dynamic speckle produced by a rotating diffuser are presented, and these agree well with theoretical predictions.
