STANDING WAVE INTERFEROMETRIC MICROSCOPE

摘要

A wide-field interferometric microscope comprising:
A specimen holder, for holding a specimen at an analysis location;An illuminator, for illuminating the specimen with input radiation, so as to cause it to emit fluorescence light;A pair of projection systems, arranged at opposite sides of said analysis location, to collect at least a portion of said fluorescence light and direct a corresponding pair of light beams into a respective pair of inputs of an optical combining element, where they optically interfere;A detector arrangement, for examining output light from said combining element,

wherein:
The illuminator is configured to produce a standing wave of input radiation at the analysis locationThe detector arrangement comprises exactly two interferometric detection branches.

1. A wide-field interferometric microscope comprising:
a specimen holder, for holding a specimen at an analysis location; an illuminator, for illuminating the specimen with input radiation, so as to cause it to emit fluorescence light; a pair of projection systems, arranged at opposite sides of said analysis location, to collect at least a portion of said fluorescence light and direct a corresponding pair of light beams into a respective pair of inputs of an optical combining element, where they optically interfere; and a detector arrangement, for examining output light from said combining element, wherein: the illuminator comprises an optical cavity that is configured to produce a standing wave of input radiation at the analysis location; and the detector arrangement comprises exactly two interferometric detection branches.
