Light source control device, operating method of light source control device, operating program of light source control device, and digital holography system

An operating method of a light source control device that controls an operation of a light source that irradiates an observation target object with illumination light to generate interference fringes of the observation target object, the light source having a configuration in which a plurality of light emitting units of the illumination light are arranged at a plurality of emission positions, the operating method comprising:

• performing control of causing the illumination light with a first set light quantity to be emitted from the plurality of emission positions one by one in order to obtain a plurality of interference-fringe images serving as a source of a super-resolution interference-fringe image with a resolution exceeding a resolution of an imaging element that picks up an image of the interference fringes;
• and
• performing at least one of
• control of setting a light quantity of the illumination light to a second set light quantity different from the first set light quantity during switching from a current emission position to a next emission position, or
• control of causing the illumination light to be emitted at a separate emission position separated by at least one emission position from both the current emission position and the next emission position during the switching from the current emission position to the next emission position.

A non-transitory computer-readable storage medium storing an operating program of a light source control device that controls an operation of a light source that irradiates an observation target object with illumination light to generate interference fringes of the observation target object, the light source having a configuration in which a plurality of light emitting units of the illumination light are arranged at a plurality of emission positions, the operating program causing a computer to execute processing, the processing comprising:

• performing control of causing the illumination light with a first set light quantity to be emitted from the plurality of emission positions one by one in order to obtain a plurality of interference-fringe images serving as a source of a super-resolution interference-fringe image with a resolution exceeding a resolution of an imaging element that picks up an image of the interference fringes;
• and
• performing at least one of
• control of setting a light quantity of the illumination light to a second set light quantity different from the first set light quantity during switching from a current emission position to a next emission position, or
• control of causing the illumination light to be emitted at a separate emission position separated by at least one emission position from both the current emission position and the next emission position during the switching from the current emission position to the next emission position.
