Large Sensitive Area
Low Dark Current
The device is built with special PIN structure, based on semiconductor transverse effect,
to be sensitive to the position of the incident light.
When light strike on the sensitive area of the device, a pair of electron and hole will
appear, the carrier reached P area can go through X1.X2，the output current of the device
have reverse ratio relationship with the position of incident light, the position of the
incident can be decided accurately.
