Optical movement sensing system |
摘要 |
There is provided an optical movement sensing system which can be miniaturized and ensures a wide angle of view. The optical movement sensing system collecting light reflected from an object to be imaged on an optical sensor, the optical movement sensing system including: a wide-angle lens including a first lens element having a curved object-side surface; and a second lens element having an object-side surface in contact with an image-side surface of the first lens element and having a planar image-side surface. The optical movement sensing system with this configuration can be reduced in size and weight and has a wide angle of view. Therefore, the optical movement sensing system is applicable to a mobile device such as a mobile telecommunication terminal and assures sufficient peripheral light amount.
