Research activities:

• Iterative technique for design of focusing DOE has been improved by use of adaptive correction and phase pixel interpolation and extrapolation.
• For iterative design of radially symmetric focusing DOE, a fast algorithm of the arbitrary-order Hankel transform has been developed.
• To attain stable operation in the presence of noise, the iterative Gerchberg-Papoulis algorithm for interferogram processing has been improved through the use of regularization procedure.
• Iterative algorithms for design of phase formers of Gauss-Hermite, Gauss-Laguerre, and Bessel modes, and multi-modal beams with invariant properties have been developed.
• Methods for optical signal analysis using the direction field and frequency field have been developed.
• Automated optical-digital systems for interpretation and recognition of structurally redundant images (fingerprints, interferograms, and crystallograms) have been designed.
