Title:
LIGHT-EMITTING MODULE, IMAGING DEVICE, AND IRRADIATION METHOD FOR LIGHT-EMITTING MODULE
Document Type and Number:
WIPO Patent Application WO/2023/189844
Kind Code:
A1
Abstract:
Provided are an imaging device, an irradiation method for a light-emitting module, and a light-emitting module excellent in spatial resolution of irradiation light. This light-emitting module comprises: a light source comprising a plurality of light-emitting elements; a control unit that is capable of individually turning on each among the plurality of light-emitting elements; a lens that transmits light from the plurality of light-emitting elements; and a drive part that is capable of relatively rotate the lens and the light source such that the optical axis of the lens or the the center axis of the light source moves on a first trajectory in a top view. After having penetrated the lens, the light from the light-emitting elements is irradiated such that the main light beam of said light moves on a second trajectory corresponding to a first trajectory, and, when the main light beam of the light moving around the second trajectory one time is defined as one cycle, the control unit is capable of changing the brightness of the light from the light-emitting elements during a plurality of divided periods into which one cycle is divided.
