PROBLEM TO BE SOLVED: To obtain phase information of object light emitted from a specimen by the non-linear type optical effect. SOLUTION: The nonlinear type microscope 101 is used for observing nonlinear object light emitted from a specimen 102 by virtue of a nonlinear optical effect after irradiating the specimen 102 with excitation lightω1 andω2. The non-linear microscope 101 includes: a galvano mirror 119 for scanning the excitation lightω1 andω2 on the observation surface of the specimen 102; a phase shifter 117 for shifting the phase of reference lightωr that has an angular frequency equal to that of the nonlinear type object light; and a detector 122 for detecting light interfering with nonlinear type object light and reference lightωr. The phase shifter 117 shifts the phase of reference lightωr by 90°each time the condensing position of the excitation lightω1 andω2 on the observation surface moves by a prescribed distance in the direction of axis x. The present invention can be applied, for example, in the nonlinear type laser scanning microscope. COPYRIGHT: (C)2011,JPO&INPIT |
