Reflection-type integral imaging system using a diffuser holographic optical element

Surface imaging using holographic optical tweezers.

We present an imaging technique using an optically trapped cigar-shaped probe controlled using holographic optical tweezers. The probe is raster scanned over a surface, allowing an image to be taken in a manner analogous to scanning probe microscopy (SPM), with automatic closed loop feedback control provided by analysis of the probe position recorded using a high speed CMOS camera. The probe is...

Holographic diffuser design using a modified genetic algorithm

Damon W. K. Wong George C. K. Chen, MEMBER SPIE Nanyang Technological University School of Electrical and Electronic Engineering Nanyang Avenue Abstract. A modified genetic algorithm is proposed for the optimization of holographic diffusers for diffuse IR wireless home networking. The novel algorithm combines the conventional genetic algorithm and the simulated annealing algorithm, in which the...

Optical Design for a Spatial-Spectral Volume Holographic Imaging System.

Spatial Spectral Holographic imaging system (S(2)-VHIS) is a promising alternative to confocal microscopy due to its capabilities to simultaneously image several sample depths with high resolution. However, the field of view of previously presented S(2)-VHIS prototypes has been restricted to less than 200μm. This paper presents experimental results of an improved S(2)-VHIS design which have a f...

Holographic Pyramid Using Integral Photography

The simple aerial display system called holographic pyramid has been eliciting much attention recently. However, the image that appears to be floating in the pyramid has no depth information because it is merely a virtual image of a 2D image displayed on a flat-panel display and reflected at the surface of a transparent board of the pyramid. Therefore, we propose a new holographic pyramid syste...
