Abstract

The lens-assisted holomicroscopic technique has been described at an earlier SPIE conference. Continuing research has led to further improvements of the lense assisted technique. In order to accommodate a larger scene volume, a scaled-up version of the lens assisted holocamera (LAH) was made. Unlike the small LAH, coherence considerations imposed greater care in spacially and temporally matching the recombined reference and scene beams. A description of the modified holocamera and the rationale for the introduction of a novel beam-splitting element is discussed. The improved holocamera has recorded a droplet spray volume of approximately one liter at a mean distance of 38 cm. The Raleigh resolutions achieved are 144 line pairs per mm or droplet diameters of 3.4 microns.
