ABSTRACT:
A single element hemispherical light detector that employs the concept of constructed occlusion to improve its uniformity of detection response across a large range of incident angles, and that incorporates a deflector to provide detection response to low incidence angles. The hemispherical light detector uses one active element or photodiode to achieve a substantially uniform response within a sector of a hemisphere.
