Abstract
An optical scanning apparatus having a linear detector array and a lens for focusing an image on the array contained within a camera housing. The housing can be rotated around a first axis so as to scan from side to side. In addition, the linear detector array can be rotated around an axis parallel to the direction of sight of the camera to enhance the signal/noise ratio.
Claims3
Optical scanning apparatus having first and second modes of operation, said optical scanning apparatus comprising:
- a camera housing;
- a linear detector array comprising a plurality of detector elements;
- at least one lens for focusing a beam of light from a direction of sight Z onto the linear detector array;
- first rotation means for rotating the camera housing around an axis N which is not parallel to the direction of sight Z;
- wherein, in order to change the angle of aperture of the optical scanning apparatus, the detector array is provided with second rotation means for rotating the detector array from a first position relating to the first mode of operation to a second position relating to the second mode of operation, around an axis which is at least substantially parallel to the direction of sight Z.
