Paper Abstract
Anti-jamming processing of optoelectronic detector signals, ensures control system invariance to change of laser power, dispersion of reflection from layer and presence of information pits. Logarithm amplification of photodetector currents stabilizes steepness of their characteristics at change of laser power (more than 10 times) and factor of reflection from surface (3 times). Besides, sections of tracing signal are chosen, which are located in intervals between information pits and free from recording. This measures increased focusing and tracking accuracy 2 - 3 times.
