Position sensitive diode(PSD)

These are Photodiodes used to detect the one-dimensional position of a spot of light on a detector surface. These are often used when it is necessary to deal with different size detector surfaces and with components that have guide holes to increase mounting accuracy. These are often used in camera automatic focusing devices.
