Abstract
An object imaging apparatus includes a housing, a light source inside the housing, a first reflector inside the housing to diffusely reflect light from the light source, a second reflector inside the housing to guide at least a part of light from the light source to the first reflector, and an imager to image an object irradiated with the light from the first reflector. A diffuse reflectance of the first reflector is higher than a diffuse reflectance of the second reflector.
