Compact multispecial scanning system. The invention relates to a compact multispectral scanning system comprising a primary mirror and secondary mirror, wherein the mirrors are facing each other, are adapted to be rotated at the same angular velocity in opposite directions, and are inclined with respect to their axes of rotation. the primary mirror is concave, the secondary mirror is smaller than the primary mirror, and the rotational axes of both mirrors are aligned. This arrangement makes the system more compact than prior art devices and avoids system dependence on operating frequency.
