IMAGE SENSING APPARATUS

摘要

An image sensing apparatus includes an optical fiber array substrate (101), a circuit conductive layer (109) thereon, an image sensor (106) arranged on the circuit conductive layer, first illumination means (104) arranged so that the incident angle with respect to the incident surface of the optical fiber is greater than a critical angle and the reflected light direction at the incident surface is not greater than the total reflection critical angle in the optical fiber inner surface with respect to the optical axis direction of the optical fiber, second illumination means (105) arranged so that the incident angle with respect to the incident surface of the optical fiber is smaller than the critical angle and the reflected light direction at the incident surface is not smaller than the total reflection critical angle in the optical fiber inner surface with respect to the optical axis direction of the optical fiber, and control means (110) for controlling ON/OFF of the illumination means. The optical axis direction of the optical fiber is arranged at a predetermined angle against a normal of the main surface of the optical fiber array substrate.
