Electrooptical and axial parallel distance measuring system

摘要

Beam source (2), transmitter optic (3), small-area photodiode (4) and receiver optic (5) have axes parallel to the measurement beam (6). This propagates directly to the object and back. Source and photodiode are rigidly connected though the circuit board assembly (8). The photodiode (at least) has contacts (10) making the electrical connection. Its temporary position (9, 9') adjustment takes place through the contacts. It is then fixed in the adjusted position, on the circuit board assembly. An Independent claim is included for the corresponding method of adjustment.
