1. Equipment for the measurement of the electromagnetic radiation coming from the half-space (corresponding to a solid angle of 2 pi) with the aid of a highly sensitive detector of low inertia arranged under a radiation-permeable dome (K), characterised thereby, that above the radiation-permeable dome (K), under which at least the one highly sensitive detector (D) of low inertia is housed, there are provided two identically or differently constructed modulators (M1, M2), which are of dome segment shape, are arranged one inside the other and which rotate at different speed in like or opposite direction about the common vertical axis (A) of both the modulators (M1, M2). |
