Title:
POLARIZATION-SPLITTING DOUBLE-SCANNING HOLOGRAPHY SYSTEM FOR REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2024/071667
Kind Code:
A1
Abstract:
The present invention relates to a polarization-splitting double-scanning holography system for a reflector. The polarization-splitting double-scanning holography system according to the present invention comprises: a scan beam generation unit which modulates the phase of a first beam split from a light source to transform the first beam into a first curvature beam and transform a second beam into a second curvature beam, and then makes the first and second curvature beams interfere with each other to form a scan beam; a scan beam splitting unit which splits the scan beam into an s-polarized beam and a p-polarized beam and projects the beams side by side; a scanning unit which receives a scan beam comprising two polarized beams emitted side by side, projects the scan beam onto an object, and controls the scanning position of the scan beam with respect to the object in the horizontal and vertical directions to transmit the scan beam to the object; and a photodetection unit which separates and detects the s-polarized beam and the p-polarized beam from the beam reflected or fluorescently emitted from the object; and a signal processing unit which processes signals of the detected s-polarized and p-polarized beams to generate a hologram of the object. According to the present invention, the hologram of the object can be acquired at ultra-high speed, faster than the scanning speed of a scanning mirror.
