Title:
METHOD FOR EYE PROTECTION FROM BLINDING OPTICAL RADIATION
Document Type and Number:
WIPO Patent Application WO/2003/045722
Kind Code:
A1
Abstract:
The method consists in that optical radiation is interrupted and dispersed in turn by each element (3) of a matrix optical shutter (2) for the account of decrease of its light transmission and transmit optical radiation to eyes through the remaining elements of the matrix optic shutter. The optic radiation reflected from the eye (23) is focused on a sensitive surface of the receiver (5) of the optic radiation and transformed into electrical signal, which is amplified and compared with a threshold level. When the threshold level is exceeded the elements of the matrix optical shutter are chosen, which have transmitted to the eyes the optical radiation from the source of the blinding, and the light transmission of the chosen elements of the matrix shutter is decreased.
