Abstract
A sensing module includes a photosensitive circuit board, a light source structure, a dimming plate, and a light-shielding plate. The photosensitive circuit board has multiple photosensitive elements. The light source structure is disposed on one side of the photosensitive surface of each photosensitive element. The dimming plate is disposed between the photosensitive circuit board and the light source structure, and includes a substrate and multiple optical microstructures. These optical microstructures are disposed on the substrate surface facing the light source structure. The light-shielding plate is disposed on the side of the light source structure opposite to the dimming plate. The light-shielding plate is adapted to be subjected to external force and pressed by the light source structure, causing deformation of the multiple optical microstructures.
