Theory of a Holographic Lens With a High Efficiency
Journal of Optics (India), 2004A two element holographic lens is proposed for obtaining high efficiency in a holographic lens. The two element holographic lens is made up of an off-axis holographic lens and a plane holographic grating. The proposed holographic lens can be used for the correction of chromatic aberration in an achromatic doublet. The theory of the holographic lens and

Applied Optics, 1995
Calculation of the optical path difference between the input and the focal planes of a lens is used to compute the phase introduced by the lens. This represents a new way to create computer-generated optical elements. The phase change that takes place during the light propagation between the computer-generated hologram and the image plane is taken into

Holographically Generated Lens
Applied Optics, 1974A holographic lens has been made that utilizes some of our earlier work on holographic aberration correction [J. E. Ward, D. C. Auth, and F. P. Carlson, Appl. Opt. 10, 896 (1971)]. The lens properties are obtained by interferometrically recording a plane wave and a pinhole generated spherical wave. The theoretical analysis is followed by the results of

Bifocal-polarization holographic lens
Optics Letters, 2004We present a holographic lens with novel features recorded in an azopolymer film. Two holographic modulations, bulk birefringence and surface relief, are induced in the medium at the same time. The resultant holographic element has two focal planes, and the polarization of light in the focal points depends on the polarization of the incident light ...

Design of a holographic lens for the infrared
Applied Optics, 1987Techniques are described for the construction of a holographic lens for focusing a collimated beam to a point. The lens is constructed in the visible for use in the near infrared. A major problem is to eliminate aberrations that result from the shift between the wavelength of construction and of use.

Holographic spatiotemporal lens
SPIE Proceedings, 2011We propose a holographic spatiotemporal lens to improve spatial resolution of two-photon excitation spot as a new focusing technique of femtosecond laser pulse. Femtosecond laser pulses dispersed by a diffraction grating are irradiated to a chirped diffractive lens displayed on a spatial light modulator.

The Journal of the Acoustical Society of America, 1978
The theory of an acoustical lens is presented and the construction of such a lens is described. In the present work three experiments are described, in which images of acoustical objects are formed. With the acosutical lens the intermediate step of the conventional acoustical holography of transfering the acoustical hologram to an optical system is ...

Photometrically corrected holographic lens
SPIE Proceedings, 2009Optical detectors for illumination measurements have the known photopic response V(λ), which is implemented with the help of colored glass filters attached to silicon detectors. In the case of high precision photometry the filter of each detector is hand prepared and the spectral response measured until it is matched to the function V(λ). This method

Demonstration holograph for comparing an image lens and a real lens
American Journal of Physics, 1977By making a holograph of a holograph, one can produce a picture in which the virtual image of a lens appears in front of a photographic plate while the images of various objects appear in or behind the plate. This virtual image of the lens has all the properties of an acutal lens when viewing these objects.

Laser Machining with a Holographic Lens
Applied Optics, 1971A holographic lens is used in conjunction with a pulsed ruby laser for machining single and multiple spots on a 0.12-microm thin film of tantalum deposited on glass. Spot sizes as small as 14 microm have been obtained with hologram diffraction efficiencies as great as 30%.
