    Abstract: An image acquisition device includes a light source, a spatial light modulator having a plurality of pixels, an objective lens for radiating the light modulated by the spatial light modulator to an observation target, a photodetector for capturing an image of the light from the observation target, and a control unit for controlling an amount of phase modulation of each pixel in accordance with a phase pattern in which phase values corresponding to the plurality of pixels are two-dimensionally distributed. The phase pattern is generated based on a predetermined basic phase pattern. The basic phase pattern includes a first region in which the phase value continuously increases in a predetermined direction, and a second region in which the phase value continuously decreases in the predetermined direction and facing the first region in the predetermined direction.

    Abstract: A light irradiation device is an apparatus for irradiating an irradiation object, and includes a light source outputting readout light L1, a spatial light modulator modulating the readout light L1 in phase to output modulated light L2, and a both-sided telecentric optical system including a first lens optically coupled to a phase modulation plane of the spatial light modulator and a second lens optically coupled between the first lens and the irradiation object, and optically coupling the phase modulation plane and the irradiation object. An optical distance between the phase modulation plane and the first lens is substantially equal to a focal length of the first lens. The spatial light modulator displays a Fresnel type kinoform on the phase modulation plane.

    Abstract: A light emission device of one embodiment reduces zero-order light included in output of an S-iPM laser. The light emission device includes a light emission unit and a phase modulation layer. The phase modulation layer has a base layer and modified refractive index regions each including modified refractive index elements.

    Abstract: The present embodiment relates to a light-emitting device or the like having a structure capable of reducing one power of ±1st-order light with respect to the other power. The light-emitting device includes a substrate, a light-emitting portion, and a phase modulation layer including a base layer and a plurality of modified refractive index regions. Each of the plurality of modified refractive index regions has a three-dimensional shape defined by a first surface facing the substrate, a second surface positioned on a side opposite to the substrate with respect to the first surface, and a side surface. In the three-dimensional shape, at least one of the first surface, the second surface, and the side surface has a portion inclined with respect to a main surface.
