A dual-mode sensor uses the active guidance radiation as a “guide star” to generate a wavefront error estimate for the primary optical element in-situ without interfering with the generation of either the active guidance or passive imaging guidance signals. An array of optical focusing elements performs the normal function of spatially encoding an angle of incidence of the active guidance radiation at an entrance pupil onto an active imaging detector. The array also performs an additional function of spatially encoding wavefront tilt deviations emanating...
1. A dual-mode sensor, comprising: a primary optical element having a common aperture for collecting and focusing active guidance radiation and passive imaging radiation along a common optical path;a secondary optical element in the common optical path, said secondary optical element separating the active guidance and passive imaging radiation and directing the active guidance radiation along a first optical path and directing the passive imaging radiation along a second optical path, said primary and secondary optical elements defining an entrance pupil...
