OPTICAL MIRROR Russian patent published in 1998 - IPC

FIELD: optical engineering. SUBSTANCE: mirror has supporting construction which carries flexible plate made of thermosensitive alloy with memory of form. Actuating mechanisms manufactured in the form of heaters are positioned on rear side of plate uniformly over its area. Supporting construction may have open towards flexible plate. Heaters made as electric spirals or graphite rods are arranged in cells. Base made of composition material with polymeric matrix and coupled to flexible plate may be introduced between flexible plate and supporting construction. Channels in which graphite rods are installed are made in base. Layer of elastic material may be positioned between base and flexible plate. EFFECT: more effective construction. 5 cl, 7 dwg
