Abstract :
Device is intended for the experimental obtaining of intensity distribution in the section of beam diffracted from pre-grooved surface. It simulates the work of laser read-out systems as at the reproduction as in the static state. It is possible to estimate the influence of optical system parameters on the values of reproduction-, servo-signals and signal/noise ratios. This device may be used for the measuring of relief microobject dimensions as well as for the optimization of optical channel and optical disc parameters and for the design of optical discs with the higher information density
