Abstract

The invention discloses a phase-shifting image digital holographic microscope system and a microscopy method thereof. The microscope system comprises a laser device, a beam dividing unit, a lighting beam transmission unit, a reference beam transmission unit, a beam combining nit and an imaging unit. The reference beam transmission unit comprises a phase-shifting device used for leading in phase shifts in reference beams. According to the phase-shifting image digital holographic microscope system and the microscopy method thereof, a phase-shifting image microscopy holographic technique is adopted, a holographic picture of an image plane is directly recorded, and phase compensation can be carried out through software to obtain precise phase information of an object.

Description

technical field [0001] The invention relates to the technical field of digital holographic microscopy, in particular to an image plane phase-shifting digital holographic microscopy system and a microscopic method thereof. Background technique [0002] At present, ordinary microscopes can only measure the intensity information of objects but not the phase information, and usually when observing biological cells, dyeing operations are required, which may destroy the structure of biological cells. [0003] The lyncee company in Switzerland invented and produced an off-axis digital holographic microscope, which records the hologram of an out-of-focus object and uses a computer to reproduce it to measure the phase information of the object. Digital holographic microscopes in the prior art have the following disadvantages: [0004] When recording off-axis, the resolution is limited and accurate measurement of the reconstruction distance is required; [0005] The existing phase-s...
