Title:
FAST-SCANNING AND THREE-DIMENSIONAL IMAGING METHOD AND DEVICE FOR LARGE-VOLUME SCATTERED SAMPLE
Document Type and Number:
WIPO Patent Application WO/2023/280292
Kind Code:
A1
Abstract:
The present application provides a fast-scanning and three-dimensional imaging method and device for a large-volume scattered sample, the method comprising: imaging the sample to obtain a light field image of the sample in different directions; rearranging the light field image to obtain sub-aperture images under different angles; obtaining a point spread function of the light field imaging system by means of computing simulation; and using an aberration estimation and synchronous reconstruction algorithm to perform three-dimensional reconstruction according to the point spread function and on the basis of the sub-aperture images. The method used in the present invention enables rapid in-situ three-dimensional imaging of the large-volume sample. A three-dimensional refractive index distribution of the sample is obtained by means of multi-angle aberration estimation, and a three-dimensional reconstruction result free from aberration is finally obtained by means of reconstruction.
