PURPOSE: To receive an optical beam constituted of many components with different wavelength, and independently direct those components by providing one or more second two-color mirrors which serially receive optical radiation transmitted through a first two-color mirror, and controlling the aiming direction of the reflected wavelength components by each two-color mirror. CONSTITUTION: An aiming device is provided with a series of aiming units p1-pN, and each aiming unit is provided with a pair of two-color mirrors 7 and 8, and those two-color mirrors 7 and 8 can rotate around their orthogonal axial lines (x) and (y) by servo mechanisms 9 and 10. Each mirror in the aiming unit p1 has a band width B1, and transmitted beam components with wavelength t1 are reflected by the mirror 7 to the mirror 8, and reflected through the mirror 8 to another unit. On the other hand, received beam components with wavelength r1 are allowed to pass through all the mirrors 8 in the aiming units p2-pn, reflected by the aiming unit p1, and reflected from the aiming unit p1 to a multiplexing device. |
