Title:
HELIOSTAT
Document Type and Number:
WIPO Patent Application WO/2011/132776
Kind Code:
A1
Abstract:
By means of a cam means, the angle of rotation pertaining to a first shaft of the disclosed heliostat causes angular adjustment of a mirror (5) in the direction of opening in a direction of rotation pertaining to the first shaft (11) and a second shaft (13) during the morning and the evening, and as a result, it is possible to cancel morning and evening aberrations. As a result, even during times of low solar elevation in the morning and the evening, the shape of a spot does not deform to an ellipse, and a clustered spot of spots having the same shape as during the daytime being in the state of being overlapped in unison becomes easily obtained.
