Imaging using volume holograms
Volume holograms can be thought of as self-aligned 3D stacks of diffractive elements that operate coherently on incident fields as they propagate through the structure. In this thesis, we propose, design and implement imaging systems that incorporate a volume hologram as one of the elements that …

Evaluation of spatial-spectral filtering in non-paraxial volume holographic imaging systems
… this thesis, the properties of transmission-mode volume phase holograms as spatial-spectral filters in optical systems for microscopic medical imaging are evaluated. In experiment, the relationship between the angle of incidence and diffraction efficiency are invesitgated for wavelength-detuned …

Design and transformation of three dimensional pupils : diffractive and subwavelength
… shape the flow of light. In diffractive regime, volume holograms are good candidates for pupils of optical imaging systems thanks to their three--dimensional structure, which provides richer design flexibility compared to conventional two--dimensional pupils. In this thesis, I will propose the …

Propagation Effect In Inhomogeneous Media, Including Media With Light-induced And Fixed Gratings
Optical waves propagation in various types of volume gratings, materials with constant impendence and optical fibers are studied. Instability of cross–phase modulation and of Energy transfer via GRON-type (Grating-type Orientational Nonlinearity in Liquid Crystal) Stimulated Scattering is …

Design and Application of Waveguide Holographic Optical Elements
Holograms formed in photosensitive materials have the ability to store both the intensity and phase information of the construction beams. Compared to the traditional optical systems, a holographic optical element (HOE) has the properties: formation in thin, lightweight films that can be deposited …
