WebAn optical head includes a blue-violet laser light source for emitting a blue-violet laser beam, a mirror with a diffraction grating for transmitting and reflecting the blue-violet laser beam at a predetermined ratio, and a front monitor sensor for receiving transmitted light or reflected light from the mirror with a diffraction grating and creating an APC signal for controlling … WebThe CD, with its closely spaced grooves and reflecting aluminium plating, acts as a diffraction grating. This accounts for the continuous spectra seen in polychromatic light. To use the CD as a grating, its surface should be masked with a black, matt paper disc from which a 0.03 x0.01 m rectangle has been cut out to nyu long island hospital new building
