Title:
GHOST IMAGING SAMPLING SYSTEM, METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/199326
Kind Code:
A1
Abstract:
The present application discloses a ghost imaging sampling system, method and apparatus. The system comprises: a processor configured to generate a plurality of modulation instructions according to light intensity distribution rules, and send each modulation instruction to a corresponding SLM; the SLMs configured to modulate the light intensity distribution of incident monochromatic light according to the received modulation instructions to obtain monochromatic modulated light; a mixed light modulator configured to mix the beams of monochromatic modulated light to obtain mixed modulated light; a light condenser configured to focus the mixed modulated light on an object to be detected; a mixed light separator configured to receive reflected mixed light reflected by the object to be detected or transmitted mixed light transmitted by the object to be detected, and separate the reflected mixed light or the transmitted mixed light to obtain beams of reflected monochromatic light or transmitted monochromatic light; and barrel detectors configured to receive corresponding reflected monochromatic light or transmitted monochromatic light, and perform light intensity measurement to obtain corresponding light intensity measurement values. The present application greatly improves sampling efficiency, accelerates a sampling process, and reduces a sampling time delay.
