Method of Structured Image Decoding at Nonlinearity of the Source–Receiver Path of Optical Radiation

The method of decoding structured images based on non-linarity compensation of the source-receiver path of optical radiation is proposed. The proposed method is much more laborious, since it requires an additional procedure of calibration of the source-receiver path of optical radiation, but it is more versatile and reliable compared to the four-step method. It is shown, that proposed method of structured image decoding can be effectively used under conditions of limited dynamic range of the receiver and with arbitrary light scattering properties of the measured object surface.
