Principles of HOLOGRAPHY

چکیده
An example of double exposure holographic interferometry. A hologram of the c-c1amp is exposed. The light source is then shuttered and the clamp tightened. A hologram of the strained c-clamp is exposed onto the same recording material. After processing, illumination of the doubly exposed hologram results in the reconstruction of two wavefronts----one corresponding to each amount of strain on the c-clamp, These two waves interfere so as to form the fringes pictured here.

Three principles of quantum gravity in the condensed matter approach
Research on quantum gravity (QG) has historically relied on appeals to guiding principles. This essay frames three such principles within the context of the condensed matter approach to QG. I first identify two distinct versions of this approach, and then consider the extent to which the principles of asymptotic safety, relative locality, and holography are supported by these versions. The gene...
متن کاملγ -Ray Holography – Three-Dimensional Imaging of a Local Atomic Structure
γ -ray holography is a novel method for three-dimensional (3D) imaging of a local atomic structure, which utilizes the internal reference idea of holography. The principles of this method will be presented with emphasis on the phase information gained by means of complex holograms.
متن کاملHolography and transmission electron microscopy
The basic principles and methods of off-axis electron holography are presented and illustrated by means of three examples related to its application in high resolution electron microscopy and the investigation of electric and magnetic fields in thin specimens.
متن کاملGeneralized Uncertainty Principle, Extra-dimensions and Holography
We consider Uncertainty Principles which take into account the role of gravity and the possible existence of extra spatial dimensions. Explicit expressions for such Generalized Uncertainty Principles in 4+n dimensions are given and their holographic properties investigated. In particular, we show that the predicted number of degrees of freedom enclosed in a given spatial volume matches the holo...
متن کاملDigital Holographic Adaptive Optics for Retinal Imaging
A new adaptive optics retinal imaging system is presented that is based on the principles of digital holography and dispenses with the wavefront sensor and wavefront corrective element of the conventional adaptive optics system. OCIS codes: 090.1995; 110.1080; 170.4470
