Position transmitter for acquiring the position of a light beam |
摘要 |
A position transmitter for acquiring the position of a light beam has at least one group of photodiodes arranged neighboring one another and fashioned strip-shaped such that at least two, typically 5-10, strip-shaped electrodes of a photodiode structure are at least partially covered by the light beam or particle beam whose position is to be acquired. An evaluation circuit measures the photocurrent or a correlated quantity of the individual strip electrodes and indicates the position of the beam on the basis of the distribution of the strengths of the photo currents.
