Abstract: Novel interferometers for length and displacement measurements based on sampling an optical standing wave will be presented. The interference of two laser beams propagating in opposite direction results in a sinusoidal light intensity profile, which can be detected by thin transparent photodiodes based on amorphous silicon. Two individual detectors positioned on he optical axis of a standing wave allow bi-directional fringe counting. The operation principle of set-ups consisting of two individual nip-photodiodes on one hand and a phase sensitive transparent photodiode based on two integrated nip-diodes on the other hand will be discussed. With both set-ups Lissajous figures are detected demonstrating the feasibility of the new concept for length and displacement measurements.
