Abstract
Abstract A position transmitter which determines the point of incidence of a light or particle beam on a sensor array, and the output signal of which gives the point of incidence in a digital code. The position transmitter comprises a sensor array having diodes which are arranged on a substrate and are connected at least partly to each other as well as to a digital bus, of which a part of the array generates electron-hole pairs if the light or particle beam strikes, and another part of the diode array arranged in accordance with the desired code is switched off in its function.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A position transmitter for determining the point of incidence of a light or particle beam on a sensor array, and the output signal of which gives the point of incidence in a digital or other desired code, wherein the sensor array comprises a plurality of diode means arranged on a substrate and connected, at least in part to each other and to a digital bus, part of the diode means generating electron-hole pairs upon the impingement of the light or particle beam, and another part of the diode means being arranged in accordance with the desired code being functionally switched off.
Claim 2
Dependent Claim
101 words
A position transmitter for determining the point of incidence of a light or particle beam on a sensor array, and the output signal of which gives the point of incidence in a digital or other desired code, wherein the sensor array comprises a plurality of diode means arranged on a substrate and connected, at least in part to each other and to a digital bus, part of the diode means generating electron-hole pairs upon the impingement of the light or particle beam, and another part of the diode means being arranged in accordance with the desired code being functionally switched off.
Claim 3
Dependent Claim
23 words
The position transmitter recited in claim 1, wherein the diode means are arranged regularly and in particular, in the form of a matrix.
Claim 4
Dependent Claim
21 words
The position transmitter recited in claim 1, wherein a further part of the diode means is connected to a trigger line.
Claim 5
Dependent Claim
48 words
The position transmitter recited in claim 1, wherein, for determining the point of incidence of a beam with elongated cross section, the other part of the diode means comprises individual array rows which are connected in parallel and are designed sensitive or insensitive, depending on the desired code.
Claim 6
Dependent Claim
29 words
The position transmitter recited in claim 4, wherein a strip diode forms the respective individual array rows which are covered up selectively against the incident light or particle beam.
Claim 7
Dependent Claim
29 words
The position transmitter recited in claim 5, wherein the strip diode is prepared by applying amorphous silicon to a glass or metal substrate with transparent contacting oxide (`TCO`) strips.
Claim 8
Dependent Claim
48 words
The position transmitter recited in claim 1, wherein the light or particle beam sensitive diodes are connected to the individual lines of a digital bus by respective diodes which are connected in series with opposite polarity and which are switched off selectively in accordance with the desired code.
Claim 9
Dependent Claim
46 words
The position transmitter recited in claim 7, wherein both the light or particle beam sensitive diodes and the respective diodes are prepared by applying amorphous silicon to a glass substrate with transparent contacting oxide (`TCO`) strips and corresponding insulation or by contacting on an opposite side.
