<p>The present invention pertains to the construction of optical instruments and may be used for obtaining thermal images of the Earth from space or from carrier aircraft of various types. The device includes a body (1), a scanning mirror (2) rigidly attached to the axis of a rotation engine (7) and arranged at an angle of 45° relative to said axis, as well as two planar mirrors (8, 9) mounted on both sides of the scanning mirror (2) opposite to each other and independently and optically connected to said scanning mirror (2). The mirrors (8, 9) extend at different angles relative to the axis of the rotation engine (7), while the normal lines to their surfaces lie in a single plane extending across the axis of the engine (7). The device further includes N cooled radiation receivers which are arranged on a line defined by the focal plane of the objective (3) and by the plane comprising the normal lines to the surfaces of the mirrors (8, 9). A corresponding filter (4) is further mounted upstream from each receiver (5).</p> |
