Claims
- 1. An optical positioning system, comprising:
- a light source means for emitting a light beam for generating a picture element in an image plane, said light source means having a variable and controllable wavelength;
- a rotatable wavelength-dispersive, light-deflecting means comprising a light-deflecting element having integrated therewith a wavelength dispersive element arranged to be impinged upon by the light beam incoming from the light source means along its rotational axis and for deflecting the incoming light beam by reflection with a mirrored surface in a basic deflection direction within a basic deflection range for setting a basic position of the picture element in the image plane based upon a rotational position of the light-deflecting means; and
- said light-deflecting means setting a position of the picture element about the basic position within the basic deflection range by its wavelength-dispersive property through setting and control of a wavelength of the light beam emanating from the light source means.
- 2. An optical positioning system according to claim 1 wherein a scan objective is positioned between the image plane and the light-deflecting means.
