Abstract
Experimental results obtained using a fine-resolution, three-dimensional imaging method are presented. The method consists of flood illuminating an extended object with a laser beam and recording the scattered light as the laser frequency is varied. An image is recovered by three-dimensional Fourier transformation of the recorded data. For the results presented here, a tunable dye-laser source is used, and the obtained range resolution is 287 μm.Keywords
