Abstract
An optical image sensing module includes a base, an optical body, at least one light emitting component, and a sensing unit. The base has a light shielding portion and a bottom portion. The light shielding portion protrudes from the bottom portion. The light shielding portion has a first opening. The bottom portion has a second opening to correspond to the light shielding portion and a third opening adjacent to the second opening. The optical body is located on the base and has a lens portion and a light guiding portion. The lens portion is connected to the light guiding portion, and is adjacent to the first opening. The light emitting component is disposed within the third opening. The sensing unit is disposed in the second opening.
Claims23
An optical image sensing module, comprising:
- a base, having a light shielding portion and a bottom portion, wherein the light shielding portion protrudes from the bottom portion, and the light shielding portion has a first opening, and the bottom portion has a second opening to correspond to the light shielding portion and a third opening adjacent to the second opening;
- an optical body, disposed on the base and having a lens portion and a light guiding portion, wherein the lens portion is connected to the light guiding portion, and the lens portion is recessed relative to the light guiding portion to accommodate the light shielding portion of the base, and the lens portion is adjacent to the first opening of the light shielding portion;
- at least one light emitting component disposed in the third opening of the base;
- and
- a sensing unit, disposed in the second opening of the base.
An optical image sensing module, comprising:
- a substrate;
- an image sensing component, disposed on a surface of the substrate;
- an infrared light source, disposed on the surface of the substrate;
- a light shielding cylinder, having a first opening and a second opening opposite to each other and disposed on the surface of the substrate, and the image sensing component located in the second opening;
- a light guiding body, located at a side of the light shielding cylinder, having a light incident surface and a light output surface;
- and
- a lens, adjacent to the first opening of the light shielding cylinder;
- wherein an infrared light generated by the infrared light source enters the light guiding body from the light incident surface, and then exits the light guiding body through the light output surface, and is reflected on a media surface, and then enters the light shielding cylinder through the lens to form an image on the image sensing component.
