The invention relates to a method for measurement of a line (S), in particular, an optical distance measurement method, whereby an input means (24,42) of a distance measuring device (20,22) is operated, which triggers a measuring sequence of distance measurements, during which individual measurements (10-16) of distances from the distance measuring device (20,22) triggered by the distance measuring device (20,22) are carried out perpendicular to the line (s) for measurement. According to the invention, at least one maximum value (10,16) and at least one minimum value of the distances are determined from the measuring sequence and the length of the line (s) determined from the at least one maximum value (10,16) and the at least one minimum value (13). The invention further relates to a distance measuring device (20,22), in particular, a hand-held measuring device for carrying out said method.

The invention relates to a method for mounting and alignment of an electro-optical apparatus, in which an optic (42) is oriented in three axes (X;Y;Z) relative to a further component (26, 46), in particular a method for alignment of a receiving optic (42) relative to an optical receiver (46). The invention proposes that the optic (42) is first aligned in a first (X) and a second direction (Y) and the optic (42) is subsequently fixed to an optical carrier (40) in the third direction (Z) by means of a welding process. The invention furthermore relates to a measuring device, in particular a distance measuring device (10), aligned according to the method of the invention.

To ensure a distance measurement in a certain, predetermined measurement time, the value on which a distance measurement is based can be adjusted to the measurement uncertainty, and can be increased incrementally in particular.

The invention relates to a device for optical distance measurement, having a emitter unit (12) having a light source (17, 18) emitting modulated optical beam (13, 20, 22) to a target object (15), and having a receiver unit (14), spaced apart from the optical axis (38) of the emitter unit (12) with at least one optical detector (54) for receiving the optical beam (16, 49, 50) returning from the target object (15), and having a control and evaluation unit (36) for ascertaining the distance (48) of the device from the target object (15). It is proposed that the active, light-sensitive face (66, 67, 68, 69) of the detector (54) of the receiver unit (14) narrows in the direction (61) of a beam displacement for decreasing target object distances (48) that is due to the parallax of the returning beam (16).
