Opto-electronic formed as reflection light scanner which receives light pulses whose polarizing direction depends on position of object; uses light pulses from transmitter directed to receivers, which on form difference signal
Opto-electronic formed as reflection light scanner which receives light pulses whose polarizing direction depends on position of object; uses light pulses from transmitter directed to receivers, which on form difference signal
Light pulses (4) from transmitter (2), are directed to a receivers (5,6), which on form a difference signal Ud or signal ratio as a measure for the relative position and/or rotational speed of an object (13).
