R. C. Fairchild* J. R. Fienup Environmental Research Institute of Michigan Radar and Optics Division P.O. Box 8618 Ann Arbor, Michigan 48107 Abstract. Holographic optical elements (HOEs) recorded with arbitrary aspheric wavefronts can now be analyzed with a holographic raytracing design program. The recording wavefronts are defined by analytical phase functions, for example, a two -dimensional ...

The performance of three optoelectronic structures incorporating substrate-embedded InP-based inverted metal–semiconductor–metal photodetectors and/or volume holographic gratings are analyzed and compared at the primary optical communication wavelengths. These structures, in conjunction with optical-quality polymer layers, can be easily integrated into silicon microelectronic substrates for the...

The preparation of neutron-optical phase gratings with light-optical holography is reviewed. We compare the relevant concepts of: (i) Kogelnik’s theory for Bragg diffraction of light by thick volume gratings, which can be used to analyze holographic gratings with both light and neutrons, and (ii) the dynamical theory of neutron diffraction. Without going into mathematical detail, we intend to i...

This chapter reviews the first ten years of interactive electro-holographic displays from its first instance in 1990 through innovations in computational approaches and optical modulation schemes. The enormous bandwidths required to image three-dimensional (3-D) holographic images interactively are examined, along with descriptions of techniques used to overcome the limitations placed upon frin...

This study proposes holographic diversity interferometry (HDI), a system that combines information from spatially dispersed plural image sensors to reconstruct complex amplitude distributions of light signals. HDI can be used to generate four holographic interference fringes having different phases, thus enabling optical phase detection in a single measurement. Unlike conventional phase-shiftin...

Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...

A recursive design technique for forming holographic elements which can be incorporated into helmet displays has been developed. To ensure that the holographic elements have low aberrations and high diffraction efficiency they must be recorded with complex wavefronts. These wavefronts are derived from relatively simple intermediate holograms whose readout geometry and wavelength differ from tho...

Two-wavelength holographic recording in thick phenanthrenequinone-doped poly(methyl methacrylate) photopolymer is demonstrated. By using 325 nm laser as a gating illumination during the holographic recording with 647 nm laser, a volume hologram with diffraction efficiency of ∼4% can be recorded in a 2 mm thick sample. In addition, the Bragg selectivity curve with clear sinc nulls is demonstrate...

Fabrication of narrow pitch grating for optical communication has been optimized using Near Field Holographic technique. Grating phase mask with pitch period of 240 nm has been used to produce grating patterns in photo resist on Si substrates using the i-line of a conventional mercury lamp as exposure light. Control of duty cycle and uniformity of the nearfield holographic gratings have been de...

Holographic interferometry with a phase-modulated reference beam is applied to an acoustic holography. A very thin, flexible, optically reflective membrane, called a pellicle, is used in the liquid as an acousto-optic interface. The method involves three processes: the motion of a pellicle caused by an ultrasonic wave is recorded as an optical hologram using holographic interferometry; the opti...
