Abstract
An object capturing device configured to capture an object present in a measurement target space includes a light emission unit, a light receiving unit, a light scanning unit configured to cause measurement light emitted at a predetermined wavelength from the light emission unit to head toward a measurement target space to perform scanning, and to guide reflected light from an object present in the measurement target space with respect to the measurement light to the light receiving unit, and a polarization filter disposed in the light scanning unit, the polarization filter including a polarizer configured to allow only light vibrating in a first direction in the measurement light to transmit, and an analyzer configured to allow only light vibrating in a second direction perpendicular to the first direction in the reflected light to transmit.
