Abstract

A twenty-five element, two dimensional array of one millimeter diameter fibers, each coupled to a photomultiplier tube, has been used to image a variety of targets with a resolution close to that obtainable with a monolithic optic of equivalent total aperture. In addition to imaging the targets, which were illuminated by coherent ultraviolet light at 353 nm, the array was used to measure both translational and rotational target motions. An optical local oscillator signal supplied to the array allowed phase-tracking across the multiple channels which permitted simultaneous imaging and Doppler-shift velocity measurements. Results for millimeter-size targets at a range of six meters from the receiver are presented.
