| 摘要 |
A multi-spectral optical sensor and the manufacturing method thereof are disclosed. The multi-spectral optical sensor includes at least one opaque base layer. Each base layer has at least two surfaces, on which optical sensing pixel groups are located. Each optical sensing pixel group is used for sensing light with any spectrum emitted from the front of the surface where the optical sensing pixel group is located. Alternatively, the multi-spectral optical sensor includes at least one transparent base layer. Each base layer has at least two surfaces, on which optical sensing pixel groups are located. Each optical sensing pixel group is used for sensing light with any spectrum emitted from the front or back of the surface where the optical sensing pixel group is located. The present invention enables sensing light from double sides by one device and sensing different images of two sides. It is also used for sensing light from one side to improve performance of the optical sensor. |
