LIGHT SOURCE CONTROL DEVICE, OPERATION METHOD FOR LIGHT SOURCE CONTROL DEVICE, OPERATION PROGRAM FOR LIGHT SOURCE CONTROL DEVICE, AND DIGITAL HOLOGRAPHY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/021795
Kind Code:
A1
Abstract:
Provided is a light source control device that controls the action of a light source configured such that a plurality of light-emitting units of illumination light are aligned at a plurality of irradiation positions, the light source generating an interference fringe of an object to be observed by irradiating the object to be observed with the illumination light, the light source control device comprising a processor, and, in order to obtain a plurality of interference fringe images that serve as a basis for a super-resolution interference fringe image exceeding the resolution of an imaging element for imaging the interference fringe, the processor performing control of irradiating, with illumination light of a first set light quantity, every one location from the plurality of irradiation positions, and performing control of setting a light quantity of the illumination light to a second set light quantity differing from the first set light quantity during switching from a current irradiation position to a next irradiation position, and/or performing control of irradiating, with the illumination light, a separated irradiation position, which is separated by at least one irradiation position from both the current irradiation position and the next irradiation position during switching from the current irradiation position to the next irradiation position.
