For optical images, a novel super-resolution method based on delaminating idea was proposed.

The paper has firstly discussed how a right wavelet base can be chosen,and decomposes the SAR image and optical image using the lifting scheme wavelet.

The data fusion of the optical image and radar image is realized by use of a method of the pixellevel based datafusion, which can extract much information and more details from two different images obtained from the same scene by the radar and optical sensors respectively.

The calculation of the polymetallic nodule s grain size and abundance from deep-tow system s optic image;

Therefore a new technique to generate the grand based millmeter wave radiometric images from visual optic images was presented.

A novel optical image encryption method and its optical implementation are proposed.

In this thesis, the research aims to combine the flexibleness of electrical equipment with the fast parallel optical computing, so that it can realize optical image encryption and recognition and high efficiency of information security protection.

The fractional Fourier Transform (FRFT) is a generalization of the conv-entional Fourier transform (FT), which is one of the most important mathematical tools used in information processing, optic systems, optical image processing and some other areas.
