摘要：
Disclosed is a device for optical scanning, comprising: a plurality of photo sensors, where the photo sensors are arranged to detect light incident on the photo sensors, emitted from a light source and reflected from an object subject to optical scanning; wherein the amount of light received at least one of the photo sensors is to a larger extent light transmitted from the light source; and to a smaller extent light reflected from the object.
