Endoscopic Imaging Using a Multimode Optical Fibre Calibrated with Multiple Internal References
The interferometric acquisition of the transmission matrix (TM) of a multimode optical fibre (MMF), which is at the heart of multimode fibre-based endoscopic imaging methods, requires using a reference beam. Attempts to use an internal reference, that is

Encoding the Intensity and Phase Gradient of Light Beams with Arbitrary Shapes
We present an approach for engineering the intensity trajectory and phase gradient of light beams with arbitrary shapes by estimating their parametric equations using Freeman chain code and by applying the fast Fourier transform.

A spatial light modulator using BSO crystals [PDF]
The combined use of the photoelectric and electro-optic properties of the Bi12SiO20 (BSO)-crystal leads to a new possibility of realizing a spatial light modulator. Under certain geometrical conditions, which will be discussed, it is possible to realize,

Holographic Display System Based on Effective Area Expansion of SLM
In this paper, a holographic display system with wide viewing area is proposed based on the effective area expansion of the SLM. The effective area of the SLM is calculated based on the viewing area characteristics and expanded by using two SLMs ...

Applications of Spatial Light Modulators in Raman Spectroscopy [PDF]
Advances in consumer display screen technologies have historically been adapted by researchers across the fields of optics as they can be used as electronically controlled spatial light modulators (SLMs) for a variety of uses. The performance characteristics of such SLM devices based on liquid crystal (LC) and digital micromirror device (DMD ...
