Three-grating monolithic phase-mask for the single-order writing of large-period gratings [PDF]

Journal of the European Optical Society-Rapid Publications, 2011
An optimized achromatic high-efficiency monolithic phase mask is presented whose principle was demonstrated and described in reference [1]. The mask comprises three submicron period diffraction gratings at a single substrate side that create a purely ...

A simple method for fabricating phase-shifted fibre Bragg gratings with flexible choice of centre wavelength [PDF]

, 2009
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same

Single-Shot Compressed Imaging via Random Phase Modulation

Applied Sciences, 2022
Compressed sensing (CS) provides an innovative framework for signal sampling, which enables accurate recovery of the sparse or compressible signal from a small set of linear measurements far fewer than the Nyquist rate in traditional signal processing ...

Exploring the prevalence and experience of mask anxiety for the person with head and neck cancer undergoing radiotherapy

Journal of Medical Radiation Sciences, 2018
Introduction While use of a thermoplastic mask during radiotherapy (RT) treatment for head and neck cancer (HNC) is an essential component of safe patient care, there is little understanding of the extent to which this evokes anxiety (i.e. “mask anxiety”)
