Abstract

The invention relates to a reflection scanning coherent diffraction microimaging device based on a broadband light source, and an application, which belong to the technical field of microimaging. Thereflection scanning coherent diffraction microimaging device comprises a wide-wavelength broadening light source, a probe light spot generation assembly, a reflection sample table assembly, a center baffle device and a signal collection and image reconstruction system which are sequentially arranged in the light beam propagation direction. The reflection scanning coherent diffraction microimagingdevice can realize reconstruction of surface structure module value information, phase information and light spot information of a sample under different wavelength modes contained in an incident light source in a form of combining reflection and scanning coherent diffraction on the basis of a non-coherent broadband light source, can judge the absorption conditions of the sample on light with different wavelengths, and has a wide prospect of applying an incoherent light source to surface structure imaging and surface element analysis.

Description

technical field [0001] The invention relates to a reflective scanning coherent diffraction microscopic imaging device and application based on a broadband light source, belonging to the technical field of microscopic imaging. Background technique [0002] The traditional coherent diffraction imaging is to irradiate the sample with coherent light, and use the charge-coupled device CCD to collect the coherent diffraction pattern of the sample in the Fraunhofer diffraction area in the far field behind the sample. Under the sampling conditions, the diffraction data can be obtained through the phase The recovery algorithm retrieves the phase information and reconstructs the spatial information of the sample. Scanning coherent diffraction imaging is a new type of coherent diffraction imaging technology based on traditional coherent diffraction imaging technology. The result is not unique and other defects. So far, scanning coherent diffraction imaging technology is becoming more...
