Title:
HEMISPHERICAL DETECTOR
Document Type and Number:
WIPO Patent Application WO2002040951
Kind Code:
A3
Abstract:
A hemispherical detector comprising a plurality of photodetectors (12) arranged in a substantially contiguous array, the array being substantially in the shape of a half-sphere, the half-sphere defining a closed end (50) and an open end (60), the open end (60) defining a substancially circular face. Also provided is a method for constructing a hemispherical detector comprising the steps of making a press mold of the desired shape of the hemispherical detector, pouring a material into the press mold to form a cast, finishing the cast to remove any defects, coating the cast with a coating material, and attaching a plurality of photodetectors to the cast.
