Abstract
A corneal endothelial cell imaging apparatus includes an irradiation system, a light receiving system, and a controller. The irradiation system includes a spatial light modulator modulating light from a light source, and is configured to irradiate slit-shaped illumination light toward a cornea by modulating the light using the spatial light modulator. The light receiving system is arranged obliquely to the irradiation system and includes an image sensor receiving reflected light from the cornea. The controller is configured to control the spatial light modulator so as to irradiate the illumination light onto an illumination region on the cornea, and is configured to control the image sensor to set an opening range on a light receiving surface corresponding to the illumination region on the cornea and to capture a light receiving result of reflection component from a corneal endothelium obtained by a light receiving element in the set opening range.
