<p>A radiometer mounted on an aircraft, satellite or similar flying body for observing reflections or radiations of visible rays or infrared rays from the land or the sea. The radiometer has optical means for receiving and converging the visible rays or infrared rays, light-sensitive elements to which the converged rays are incident, means for changing the optical distance between the light-sensitive elements and the optical means, and means for generating correction data while the focal distance of the optical means is deviated from the light-sensitive surface of the light-sensitive elements. <IMAGE></p> |
