IR Position Detector

Opto-electronic measuring instrument for registering the oscillations of gravitation torsion balances. Measuring principle: four IR-diodes successively emit infrared light, which is reflected onto a row of phototransistors by the concave mirror mounted on the gravitation torsion balance. A microcontroller determines which phototransistors are illuminated. These measurements permit determination of the main focus of the illumination. Data are recorded using a TY-recorder, or alternatively using an MS-DOS computer via the RS-232 serial interface. (The apparatus is supplied with a disk containing a Windows program for direct measured-value acquisition and evaluation, as well as the source code for using the IRPD under Turbo Pascal. The source code plus documentation serve as a description of the interface, for creating programs for any computers and programming languages.)
