Abstract
PURPOSE: To detect minute defects of a body with high accuracy by irradiating small spot light to a body to be detected.
CONSTITUTION: A light ray from a luminous source 2 is irradiated onto a body 1 to be detected (the case of using a glass tube as a body to be detected is shown) as small spot light through a spot plate 3 and an optical filter 4. A transmitted image or a reflected image of the body 1 to be detected, formed by spot light, and converted into electrical signal information through a photoelectrical converting element array 5. The minute defects of the body 1 to be detected are detected from the electrical signal by signal processing means such as a video circuit 6, a sample holding circuit 7, a comparison circuit 8, a control circuit 9 and the like.
