Abstract

Imaging correlography is a technique for recovering images of coherently illuminated objects from pupil plane measurements of the backscattered laser-speckle intensity.¹ In this paper, we describe the implementation of the imaging correlography technique using a one-dimensional (linear) receiver array. Two-dimensional images are reconstructed from intensity data that is collected and processed in the form of an inverse synthetic aperture. The synthetic aperture is produced by the motion of the object (with respect to the receiver) which causes the backscattered intensity pattern to “sweep” across the linear array.
