| 摘要 |
The structure according to the invention comprises a tubular optical collector including, between an inlet orifice 2 and an outlet orifice 3, a reflecting internal wall, the profile of which is optimised for injecting a concentrated radiation flux within the integration cavity 16 of coupled focusing means, in a removable manner, onto the said collector. At least the sensitive surface 31 of a photon detector 30, which surface is oriented obliquely with respect to the axis of revolution XX' of the collector 1, is extended inside the cavity 16. This structure can be fitted to infrared detectors of the photovoltaic type, to photoconductors, to bolometers, and to semiconductor X-ray or heat detectors. <IMAGE>
