Abstract
A sensing device includes a housing and an image sensing system disposed in the housing and used for detecting a reflected light from an object. The image sensing system includes a substrate, a light sensing element, and a reflection and redirection element. The light sensing element is disposed on the substrate. The reflection and redirection element is disposed between the light sensing element and the object, and used for reflecting and redirecting the reflected light from the object to a receiving direction of the light sensing element, such that the light sensing element receives the reflected light and generates a corresponding sensing signal.
Claims19
An image sensing system, applicable in a sensing device, for detecting a reflected light from an object, the image sensing system comprising:
- a substrate;
- a light sensing element, disposed on the substrate, and having a receiving direction;
- and
- a reflection and redirection element, disposed between the light sensing element and the object, and corresponding to the receiving direction of the light sensing element;
- wherein the reflection and redirection element reflects and redirects the reflected light to the receiving direction, and the light sensing element receives the reflected light and generates a corresponding sensing signal.
A sensing device, comprising:
- a housing, having an accommodation space therein, and having a through hole;
- and
- an image sensing system, disposed in the housing, for detecting a reflected light from an object, the image sensing system comprising:
- a substrate;
- a light sensing element, disposed on the substrate, and having a receiving direction;
- and
- a reflection and redirection element, disposed between the light sensing element and the object, and corresponding to the receiving direction of the light sensing element;
- wherein the reflected light from the object passes through the through hole and enters the housing, the reflection and redirection element reflects and redirects the reflected light to the receiving direction, and the light sensing element receives the reflected light and generates a corresponding sensing signal.
