Abstract
A scanning apparatus to scan an object by means of a light beam (B), provided with a housing (40), a light source (1) for generating the light beam (B), at least one mirror (6) for receiving and reflecting the light beam (B), which mirror (6) is, in operation, driven by first driving means (20) through a shaft (21) for continuous rotation about an axis of rotation (x) and by second driving means (30) by means of a carriage (117, 118) arranged on the shaft (21) such that the carriage (117, 118) and the shaft (21) are slidable relative to one another in an axial direction along the axis of rotation (x) for pivoting the at least one mirror (6) relative to the axis of rotation (x) about a pivoting point (102), a holder (115, 415) contacting the carriage (117, 118) by means (116) allowing the shaft (21) and the carriage (117, 118) to rotate concurrently within the holder (115, 415) and such that the holder (115, 415) and the shaft (21) can be shifted relative to one another in the axial direction.
