General theory of three-dimensional radiance measurements with optical microprobes

Abstract

Measurements of the radiance distribution and ?uence rate within turbid samples with ?ber-optic radiance microprobes contain a large variable instrumental error caused by the nonuniform directional sensitivity of the microprobes. A general theory of three-dimensional radiance measurements is presented that provides correction for this error by using the independently obtained function of the angular sensitivity of the microprobes
