A optical system carried by a flying object such as a satellite or aircraft having a pair of optical paths having different Q values for obtaining a pair of images of the same spot on the Earth's (or other celestial body's) surface. The optical paths may have a portion in common with each other and a portion not in common with each other. Light is directed into the optical paths via a field sharing arrangement. One of the optical paths together with an imaging device creates relatively narrower field of view images with a higher ground resolution than the other optical path together with an imaging device. |
