POINT SCAN TYPE IMAGING APPARATUS FOR IMAGING TARGET OBJECT WITHIN MEDIA WITCH BRING ABOUT ABERRATION

摘要

The present invention relates to an imaging apparatus of a focal scan method for imaging a target object in a sample causing aberration, comprising: a light source unit irradiating a beam; a beam irradiated from the light source unit is divided into a sample wave and a reference wave; an optical interferometer for forming an interference wave between the reflected wave reflected from the sample and the reference wave; a camera module for photographing the interference wave; A scanning mirror for reflecting the sample wave to scan a sample, a wavefront shape modulator disposed on an optical path of the sample wave of the optical interferometer, and a phase map calculation for calculating an aberration correction phase map for correction of sample-induced aberration an imaging control unit operating in an imaging mode in which the aberration correction phase map is displayed on the wavefront shape modulator to image the target object in a state in which the sample-induced aberration is corrected; The imaging controller controls the wavefront shape modulator to operate as a mirror in the phase map calculation mode, and calculates the aberration correction phase map based on a CLASS algorithm.
