Apparatus, for recording a hologram by simultaneously exposing a given area of a hologram recording medium to an information carrying beam and a reference beam of coherent radiation to produce an interference pattern from which an image can be reconstructed with a predeterminable ultimate resolution ...

Schemes for recording and reconstruction of relief-phase reflection holograms providing virtually aberration-free imaging of the structure of two-dimensional objects were developed and substantiated. Samples of relief-phase reflection holograms forming a speckle-free image of a photolithographic test pattern ...

coherent source systems avoid speckling tend to result in blurred images with a lack of contrast. By building an algorithm specific to the physics of partially coherent light sources, the researchers have produced the first high-quality and speckle-free holographic 2D and 3D images using LEDs and...

The invention discloses a speckle-free three-primary-color laser light source, which comprises a plurality of laser modules, an energy-transfer fiber, a converging lens, a diffusion sheet and a rectangular integrating rod, wherein an output fiber outlet of each laser module corresponds to one co...
However, it has been challenging to implement the true 3D holography with high-reconstruction quality due to the speckle. Here, we propose the practical solution to realize speckle-free, high-contrast, true 3D holography by combining random-phase, temporal multiplexing, binary holography, and binary...

Its wide spectral width ensures low coherency, which is critical for speckle free imaging. A high brightness and well-collimated output beam allow for projection of the illumination across long distances. In this project, a high brightness SLED chip that exceeds 200 mW in peak optical power ...
