Abstract
A camera system configured to inspect an inspection target moving in a first direction includes an illumination unit configured to irradiate the inspection target with a terahertz wave, and a camera unit disposed at a position which the terahertz wave reflected on the inspection target enters, and configured to acquire an image formed by the reflected terahertz wave. The illumination unit includes a plurality of illumination elements two-dimensionally arranged in the first direction and a second direction different from the first direction. Angles formed between directions of optical axes of the plurality of illumination elements arranged in the second direction projected onto a first plane that includes a straight line in the first direction and a straight line in the second direction and the first direction become smaller as a position approaches a center portion of the plurality of illumination elements arranged in the second direction.
