Title:
OPTICAL SENSING SYSTEM
Document Type and Number:
Japanese Patent JP2022140317
Kind Code:
A
Abstract:
To provide an optical sensing system, which includes a light source, a projection module, and a sensing module.SOLUTION: A light source is configured to provide illumination light beam. A projection module is disposed on a transmission path of the illumination light beam. The illumination light beam is transmitted to a target object by the projection module. The target object reflects the illumination light beam to generate a sensing light beam. A sensing module is disposed on a transmission path of the sensing light beam. The sensing module includes at least one sensing unit. Each sensing unit includes a light receiving element and a sensing element, and the sensing unit has an optical axis. The light receiving element is located between the target object and the sensing element, and is configured to guide the sensing light beam to the sensing element along the optical axis. The light receiving element has a focal point on the optical axis, and the sensing element is not located at the focal point. An optical sensing system according to the present invention can increase an amount of the received optical signal to increase optical sensing effect.SELECTED DRAWING: Figure 1
