DEVICE AND PROCESS FOR MEASURING THE ANGLE OF ROTATION OF TWO OBJECTS ROTATING IN RELATION TO EACH OTHER |
摘要 |
Measurement of the rotating angle of two objects rotating in relation to each other is achieved with a transmitter assigned to one of the objects. The transmitter emits light that is either polarized or becomes polarized by means of a polarization filter, and with a polarization-sensitive polarizer such that the transmitter and the polarizer rotate relative to each other as dependent on the rotating angle. A receiver measures the luminosity of light passing through the polarizer in order to create a signal that is dependent on the rotating angle, and where the receiver has at least two receiver elements which detect light of differing polarization.
