HIGH RESOLVING POWER MICROSCOPE AND PHASE RELAXING TIME MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a high resolving power microscope capable of observing the non-linear optical response of a sample with high space resolving power and high time resolving power. SOLUTION: The high resolving power microscope is equipped with an incoherent beam source 1 for generating incoherent beam, a beam splitter 7 for splitting incoherent beam into two incoherent beams, a beam delay circuit 20 for temporally delaying one split incoherent beam A, a light path length control means 10 for cyclically changing the light path length of the other split incoherent beam B to control the delay time of the incoherent beam B, and an optical probe 30 irradiating the sample to be measured with incoherent superposed beam obtained by superposing the incoherent beams A and B one upon another through a near field.
