摘要：

A specific class of paraboloidal reflectors namely the offsetfeed paraboloidal reflectors which find application in space communications is utilized for concentrations of solar energy at a fixed point (focus) maintained throughout the day in shade. The energy distributions on spherical receiver centered around the focus and on a flat sectorial receiver held in a plane perpendicular to the focal line have been studied for the case of perfect tracking in hour angle and declination axes. The spill-over of energy due to non-tracking in hour-angle or declination axis for specific periods in the case of a flat sectorial receiver has been studied and plotted. A summary of the results and suggested applications of this configuration are presented. A comparison of performance is made between wedge-type and circular aperture type offsetfeed reflectors. 3 refs.
