Abstract

A method for measuring focal distance of a thermal lens located in an analyte, the method including: providing an exciting optical beam passing through the analyte and creating the thermal lens therein; emitting a coherent probe optical beam passing through the analyte and being propagated substantially perpendicular to the exciting optical beam; intercepting the probe optical beam by a detector after passing through the analyte; focusing the probe optical beam upstream or downstream of the thermal lens such that only a fraction of the probe optical beam passes through the thermal lens; acquiring an interference image by the detector; and processing the interference image to calculate the focal distance of the thermal lens. Such a method may find application in physico-chemical analysis of the analyte.
