Ring-shaped bifocal lens used for fluorescent self-referenced holographic imaging [PDF]
We propose an alternative and simple solution to self-referenced digital holographic imaging based on a ring-shaped bifocal lens, without the need of any mirrors, polarizers or spatial light modulators.

Covariant Holographic Renormalization of Non-Conformal Field Theories [PDF]
We present a Covariant Holographic Renormalization (CHR) procedure of fake supergravity (sugra) systems. Holography is a strong/weak coupling duality between gravitational and gauge theories, and fake sugra is a theory of gravity coupled to scalars in ...

A non-coherent holographic correlator based on a digital micromirror device [PDF]
The possibility of application of a digital micromirror device (DMD) as a spatial light modulator for outputting holographic filters in an optical correlator illuminated by quasi-monochromatic spatially incoherent radiation was discussed.
