ULTRA-HIGH-SPEED, HIGH-PRECISION, THREE-DIMENSIONAL REFRACTIVE INDEX MEASUREMENT METHOD AND DEVICE USING WAVEFRONT SHAPER

摘要

An ultra-high-speed, high-precision, three-dimensional refractive index measurement method and device using a wavefront shaper are disclosed. The ultra-high-speed, high-precision, three-dimensional refractive index measurement method using a wavefront shaper can comprise the steps of: changing the irradiation angle and/or a wavefront pattern of incident light beams so as to make the light beams incident to a sample, by using the wavefront shaper; measuring, according to at least one of the incident light beams, a two-dimensional optical field having passed through the sample, by using an interferometer; and acquiring a three-dimensional refractive index image through the information of the measured two-dimensional optical field.
