Developing and testing of a prototype electro-optical phase encoded position transducer
Abstract
dc:description.abstractA proof-of-concept experimental validation of a proposed idea for a prototype electro-optical phase encoded position transducer was conducted. The intensity of two IR LED beams were modulated sinusoidally at frequency omega, with a 90 degree temporal phase difference. They further modulated by a pair of sinusoidal optical encoding masks with 90 degree spatial phase difference. The mask pair was mounted on a mechanical tage and translated perpendicular to the beam axis. The sum of the two signals produced by this electro-optical configuration constituted another sinusoid at temporal frequency omega, whose phase was proportional to mask position. Although small deviations from ideal behavior were observed, the validity of the technique has been established incontestably.
