Abstract

A hybrid optical-digital approach is being investigated for a real time Kalman, 2-D, nonlinear phase estimator. The 2-D convolution is calculated using incoherent optics with an LED array input and a CCD array output. Interfacing problems and the accuracy of the optical convolution are discussed.
