Spectral detector with angular resolution using refractive and reflective structures

Abstract

A detector for receiving light impinging at a reception point and for measuring, for a plurality of angles of incidence, at least one property of the light. The detector includes a plurality of light sensors, each of which is associated with an acceptance interval (which defines the angle of incidence which a light beam must have to reach the light sensor) and at least two acceptance intervals are different from one another. The detector further includes an optical conductor for conducting a light beam from the reception point to a particular light sensor, but only if the angle of incidence of the light beam belongs to the acceptance interval associated with the particular light sensor.
