Title:
GEOMETRIC PHASE IN-LINE SCANNING HOLOGRAPHY SYSTEM FOR TRANSMISSIVE OBJECT
Document Type and Number:
WIPO Patent Application WO/2022/035068
Kind Code:
A1
Abstract:
The present invention relates to a geometric phase in-line scanning holography system for a transmissive object. According to the present invention, is provided a geometric phase in-line scanning holography system for a transmissive object, comprising: a polarization sensitive lens, which receives a linear polarization beam to generate a first spherical wave of right-sided circularly polarized light having a negative focal distance and a second spherical wave of left-sided circularly polarized light having a positive focal distance; a scan means for scanning the transmissive object by using an interference beam generated between the generated first and second spherical waves; a first beam splitter, which receives a beam having been transmitted through the transmissive object, so as to split the received beam into first and second output beams; first and second polarizers for polarizing the first and second output beams, respectively; and first and second photodetectors for detecting output beams having passed through the first and second polarizers.
