Image decoders encoders and transcoders incorporate gamut transformations. The display unit stereoscopically displays an aggregation of a plurality of cubes in three-dimensional space. The valve assembly is in fluid communication with the valve assembly and the actuator. The distance between wavelengths can be tailored for the specific laser and application by altering the number of times the beam strikes the diffraction gratings, the groove density of the gratings and the focal length of the lens.
