Abstract: A method for compensating beam angle variation of a beam bundle of laser beams with respective beam angles includes generating the beam bundle using a diffractive optical element, determining a beam angle value from a beam angle of at least one laser beam of a first subset of the laser beams, detecting a light pattern projected by a second subset of the laser beams, and evaluating the light pattern. The evaluation is performed taking into account the beam angle variation of the beam angles of the second subset of the laser beams on the basis of the determined beam angle value.

Abstract: A method for detecting a distortion of a light pattern defining a code word includes projecting a light pattern onto an object via a light source and detecting the projected light pattern and comparing the detected light pattern with a reference light pattern. The reference light pattern has individual, spaced-apart light pattern elements arranged in a plurality of successive columns in the direction of a first extension axis and the number and/or position of the at least one light pattern element in each column of the reference light pattern is an encoding feature that defines at least one code word. The distortion of the detected light pattern with respect to the reference light pattern is determined by comparing distances between the light pattern elements of the detected light pattern with distances between the light pattern elements of the reference light pattern.

Abstract: A method for measuring the height of an object, including projecting a light pattern having successive coded picture elements extending in a direction of a transversal axis onto the object by a light source. Each of the picture elements has at least one coding feature and the picture elements together define a code word. The picture element groups from a sequence of a predetermined number of successive picture elements each define individual partial code words, existing exactly once within the code word. Capturing the light pattern by a picture sensor arranged off-set to the light source. Determining the positions of the picture element groups and determining the height of the object the determined position of the picture element groups in comparison to a respective reference position.

Abstract: The present invention relates to an imaging optical system for imaging the peripherally extending lateral surfaces (9) of an object (10) on to an imaging plane, comprising a reflecting element (6) and a first angle-reducing element (3, 17) which is arranged downstream of the reflecting element in the beam direction and which reduces the angle between a light beam emanating from the object (10) and the optical axis (12). In order to provide an imaging optical system for imaging the peripherally extending lateral surfaces of objects, which is both simple and inexpensive to produce and also has a large acceptance angle for the incident radiation and which is tolerant in relation to inaccurate positioning of the object, it is proposed in accordance with the invention that arranged upstream of the reflecting element (6) in the beam direction is a second angle-reducing element (13) which reduces the angle between a light beam (1, 1) emanating from the object (10) and the optical axis (12).
