ABSTRACT:
A light detector (10) comprising a detector cell (12); a system for focusing light (14, 16, 18) on the cell; a liquid crystal (22) positioned in the light path; the liquid crystal (22) being prepared so that it passes light along the light path in the normal operating range of the detector cell (12) and directs light away from the light path when a threshold intensity of light is reached; and source of bias (24) across the crystal to enhance the recovery of the crystal (22).
