METHOD OF PROTECTING RECEIVER OF OPTICAL RADIATION Russian patent published in 2017 - IPC H04N5/238 H01L31/232 

FIELD: physics.

SUBSTANCE: method includes receiving an input optical stream by a matrix photoreceiver (MFR), measuring the value of i_i output signal of each i-th sensing element (SE) of the MFR, where is the SE MFR number, N is the number of SE in the MFR, and a comparison of their value with the threshold value i_p. When the value of i_j output signal of the j-th SE of the MFR of the threshold value i_p closing the j-th part of the input optical stream. Next, the j-th part of the input optical flux is periodically opened and the values of ij output signal of j-th SE MFR. When i_j≥i_p, the j-th part of the input optical flux is closed, and for i_j<i_p the j-th part of the input optical flux is left open.

EFFECT: to operate the device in conditions of illumination photosensitive surface powerful signals.
