Optical scanning system with wavelength shift correction |
摘要 |
A spot scanning holographic spinner system incorporates an optical element in the optical path to provide compensation for wavelength shifts in the coherent light source. The device is located in a plane parallel to the spinner and consists of a diffraction grating having the same properties as gratings formed on the spinner surface.
