Abstract: The invention relates to a device for alignment of a first component (1; 25) and a second component (2; 26) in a predetermined relation to each other, comprising first measuring unit (7; 7?; 7?) arranged to be mounted on said first component (1; 25) and comprising a light-source (9) for generation of light-radiation (10; 10?) with a predetermined pattern in direction towards a second measuring unit (11; 11?) arranged to be mounted on said second component (2; 26) and also comprising a second light-source for generation of light radiation (13; 13?) with a predetermined pattern in direction towards said first measuring unit (7; 7?; 7?), were each of the measuring units (7, 11; 7?; 7?, 11?) comprises a detection device for emitted light radiation. The invention is characterized in that each of the measuring units (7, 11; 7?; 7?, 11?) comprises at least one reference component (18a, 18b, 19a, 19b) which during said alignment is connected with a predetermined position on respective component (1, 2; 26, 26).

Abstract: The invention relates to a device for alignment of a first component (1) and a second component (2) in a predetermined relation to each other, comprising a transmitter unit (7) arranged for mounting on said first component (1) and comprising a light source (9) for the generation of light radiation (10) with a predetermined pattern in the direction towards a receiver unit (11; 11?, 22, 27; 27?) arranged for mounting on said second component (2), where the receiver unit (11; 11?) comprises a detection device (18a, 18b; 18a?, 18b? 23a, 23b; 28a, 28b; 28?a, 28?b) for said light radiation (10). The invention is characterised in that said detector device (18a, 18b; 18a?, 18b?, 23a, 23b; 28a, 28b, 28?a, 28?b) comprises a first detector (18a, 18a? 23a; 28a; 28a?) and a second detector (18b; 18b? 23b; 28b; 28?b), respectively, which are separated depthwise in relation to said transmitter unit (7).
