INTERFEROGRAM PICTURE REPRODUCER Russian patent published in 1995 - IPC

FIELD: television engineering. SUBSTANCE: interferogram picture reproducer has optically coupled gates (or pulsed light source) and charge-coupled array built up of charge-coupled first storage section and output register, control unit, preamplifier, and viewing monitor unit; it is also provided with series-arranged and optically coupled light splitter and light-control cell inserted between gate (or pulsed light source) and CCD array and second storage section inserted in CCD array which is charge-coupled with first storage section and output register. Novelty in reproducer is provision for recursive filtering of current and frame-delayed picture signals in CCD array with charge components without additional transformation of delayed signal. EFFECT: improved reproducing accuracy under random oscillations of equipment under check, more reliable validity of interferogram monitoring, reduced execution time. 3 cl, 5 dwg
