Abstract (en)

[origin: WO2020156892A1] The invention relates to a position detection device (60) for a light signal deflection device (34, 40) of an optical measurement apparatus (12) for detecting objects (18) in a monitored region (16), a light signal deflection device (34, 40), an optical measurement apparatus (12) and a method for operating a position detection device (60). The position detection device (60) is designed to provide at least one position signal (68) which corresponds to a deflection (72) of at least one deflection region (42a, 42b) of the light signal deflection device (34, 40). The at least one deflection region (42a, 42b) is used to deflect at least one light signal (20, 22) and is rotatable in at least one direction of rotation (48) over at least some of the circumference with respect at least one axis (46). The position detection device (60) has at least one position region (62), which is mechanically coupled to the at least one deflection region (42a, 42b) of the light signal deflection device (34, 40) in such a way that the at least one position region (62) can also carry out rotations of the at least one deflection region (42a, 42b). The at least one position region (62) is designed to provide at least one position signal (68) which corresponds to a deflection (72) of the at least one deflection region (42a, 42b). The at least one position region (62) has at least one diffractive structure (63), which is configured such that light signals (20) can be shaped to form position light signals (68) depending on the incidence (52, 53) thereof on the at least one position region (62).
