摘要： A device for determining a position of an object (25) in a spatial region (28) comprises a light source (3), a light directing device (4-9), at least one reference signal detector (11, 12) and a detector arrangement (13, 14). The light source (3) generates a sequence of light pulses with a repetition rate. The light directing device (4-9) directs the sequence of light pulses into the spatial region (28) and, as a reference signal (20), to the at least one reference signal detector (11, 12). The detector arrangement (13, 14) detects a plurality of light signals (23, 24) which are reflected and/or scattered by the object (25) in the spatial region (28) into a plurality of different directions by reflection and/or scattering of the sequence of light pulses. The evaluation circuit (15) is coupled to the detector arrangement (13, 14) and the at least one reference signal detector (11, 12) and determines a phase difference (67) between the reference signal (20) and a signal component of at least one light signal (23, 24). The phase difference is determined based on the signal component which has a frequency that corresponds to a multiple of the repetition rate.

摘要： A device for measuring a surface (2) comprises a light source (3), a light directing device (4-6), a detector arrangement (10) and an evaluation circuit (15). The light source (3) generates a sequence of light pulses with a repetition rate. The light directing device (4-6) is controllable to direct the sequence of light pulses onto a surface area (25) of the surface (2). The surface area may be selected from plural surface areas (25, 27). The detector arrangement is configured to receive at least one light signal (21-24) scattered and/or reflected by the surface area (25). The evaluation circuit (15) is coupled to the detector arrangement (10) and is configured to determine a phase difference between a reference signal (19) derived from the sequence of light pulses and a signal component of the at least one light signal (21-24), in order to determine a position of the surface area (25). In doing so, the phase difference is determined for the signal component which has a frequency corresponding to a multiple of the repetition rate.

摘要： An evaluation device for path length measurement configured to evaluate a measured signal representing an intensity of a sequence of pulses of electromagnetic radiation, particularly a sequence of light pulses, as a function of time, after the sequence has traveled through a path length to be measured. The sequence of light pulses is generated with a repetition rate by a radiation source, particularly a light source. The evaluation device is configured to evaluate a first component of the measured signal, which oscillates with a first frequency, and a second component of the measured signal, which the second component oscillates with a second frequency that is greater than the first frequency. The first frequency may correspond to the repetition rate or a multiple of the repetition rate. The second frequency may correspond to another multiple of the repetition rate.
