HIGH SPACE RESOLUTION LIGHT SOURCE FOR MEASURING LIGHT WAVE FAULT IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a high space resolution light source for measuring light wave fault images that can reduce costs, can be miniaturized, can reduce weight, and can simplify a light source.;SOLUTION: The high space resolution light source for measuring light wave fault images comprises: wideband mirrors 13, 19; a laser crystal 15 for generating wideband fluorescence that is arranged between the wideband mirrors 13, 19; and a light wave phase control element 16 that is arranged between the wideband mirrors 13, 19, thus generating a light wave having a high spacial coherence with a wide spectrum.;COPYRIGHT: (C)2004,JPO
