Endoscopic Imaging Using a Multimode Optical Fibre Calibrated with Multiple Internal References

open access: yesPhotonics, 2022
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

open access: yesApplied Sciences, 2023
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]

open access: yes, 1986
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,
