Longitudinal spatial coherence of the optical field and its effects in the interference microscopy
- Conference date: 14–17 May 2012
- Location: Saint Petersburg, Russia
The results of theoretical and experimental investigation of longitudinal spatial coherence of an optical field with broad enough angular and frequency spectra and effects of its manifestation in the interference microscopy are presented and discussed. The method for compensation of so-called defocusing effect in interference microscopy which can be applied to simultaneous determination of geometrical thickness and refractive index of a tested layer object has been proposed.
