High-precision and real-time remote sensing imaging system is an important part of remote sensing development.
Holography is a method of wave front record and recovery which was presented by Dennis Gabor. As a new kind of
holography techniques, Optical scanning holography (OSH) and remote sensing imaging are intended to be combined
together and applied in acquisition and interference measurement of remote sensing. The key principles and applicability
of OSH are studied and the mathematic relation between Fresnel Zone Plate number, numerical aperture and object
distance was deduced, which are proved to be feasible for OSH to apply in large scale remote sensing. At last, a new
three-dimensional reflected OSH remote sensing imaging system is designed with the combination of scanning technique
to record hologram patterns of large scale remote sensing scenes. This scheme is helpful for expanding OSH technique to
remote sensing in future.
It is the coexisting time between film and digital imaging. Both film aerial camera and digital one have their particular
imaging principles, characteristics and complementarities between them. In this paper, a new convertible aerial camera is
developed to integrate film and CCD sensors, named as twice-imaging scheme. Some experiments have been carried out
for the feasibility of the scheme. This convertible aerial camera system has both film and digital advantages. It can be
used in different aspects of aerial remote sensing, surveying and mapping.
