Abstract

The invention relates to an image detecting device comprising an illuminating system and a sensing system, wherein the illuminating system is used for supplying a light beam to a reflecting surface inorder to generate a reflecting light beam; the sensing system comprises a sensing element and a focusing element, the sensing element is arranged on a transmitting path of the reflecting light beam to receive the reflecting light beam, the focusing element is arranged between the sensing element and the reflecting surface, and an optical axis of the focusing element deviates a primary optical axis of the reflecting light beam. Because the optical axis of the focusing element deviates from the primary optical axis of the reflecting light beam in order to reduce the optical path difference of light beams of the reflecting light beam, the image detecting device has optimal imaging quality.

Description

technical field [0001] The invention relates to an image detection device, in particular to an image detection device with good imaging quality. Background technique [0002] see figure 1 , figure 2 as shown, figure 1 is a structural schematic diagram of a known image detection device, and figure 2 is the beam in figure 1 Schematic diagram of the sensing system. The conventional image detection device 100 includes an illumination system 110 and a sensing system 120 . The lighting system 110 includes a light source 112 and a lens 114 , wherein the light source 112 is used to provide a light beam 113 , and the lens 114 is arranged on the transmission path of the light beam 113 . Beam 113 has an optical axis 113a, and in figure 1 The light beam 113 is represented by the optical axis 113a in the figure. The sensing system 120 includes a sensing element 122 and a lens 124 . The sensing element 122 and the lens 124 are arranged on the transmission path of the light beam...
