METHOD AND APPARATUS FOR THREE-DIMENSIONAL MICROSCOPY WITH ENHANCED DEPTH RESOLUTION

摘要

A method and apparatus for three-dimensional optical microscopy is disclosed which employs dual opposing objective lenses (70, 72) about a sample (94) and extended incoherent illumination (84) to provide enhanced depth resolution. The observed light from both objective lenses is brought into coincidence on an image detector (128) and caused to interfere thereon by optical path length adjustment (138).
