Biese Betektoren liefern Impulse, die nach Parallelschaltung im binaren Code den Ort der Lichtquelle angeben. Auf dies· Veise ergibt sich eine Information, die den Ort der "Lichtquelle geaSes einer Koordinatenachse anglht, wonach die Information gemaas fe 10 der zweiten Achse mittels einer zweiten'Codeplatte erhalten wird, die gleich der ersten ist, jedoch in ihrer Ebene um 90* gedreht ist. Auf diese iVeise kinnen die x- und y-Koordinatem der Lichtquelle genau in binärer Code bestimmt werden.These actuators deliver impulses after parallel connection specify the location of the light source in binary code. On this· Veise results in a piece of information indicating the location of the "light source geaSes anglht a coordinate axis, after which the information gemaas fe 10 of the second axis is obtained by means of a second code plate, which is the same as the first, but rotated by 90 * in its plane. In this way, the x and y coordinates of the light source can be precise can be determined in binary code.
