Fibre optic sensors: a review of today's applications

The purpose of this paper is to review the applications of commercially available fibre optic sensors (FOSs) and consider the reasons for their use.

Developments in electromagnetic radiation sensing. Part two: long wavelengths

The purpose of this paper is to review recent developments in the sensing of electromagnetic radiation (EMR) with wavelengths longer than those of visible light.

Imaging a rectangular fluidised bed by electrical capacitance tomography: preliminary results

Rectangular fluidised beds are commonly used in industry, e.g. circulating fluidised bed (CFB) boilers. Apparently, no one has tried to imagine rectangular fluidised beds by…

The purpose of this paper is to present a review of research performed at the Communications Research Centre Canada on sensing applications of femtosecond infrared laser‐inscribed…

A novel detection and navigation approach based on OWA fusion method

The purpose of this paper is to design and implement a landmine detection robot (Venus) equipped with three electromagnetic sensors and controlled by ordered weighted averaging…

A fast and effective approach to generate true orthophoto in built‐up area

Orthophoto suffers from the relief displacement effects magnified by high resolution imaging sensors especially when mapping urban areas. True orthophotos eliminating relief…

Robust watermarking in wavelet domain based on chaotic scrambling

The purpose of this paper is to present an imperceptible and robust watermarking algorithm with high embedding capacity for digital images based on discrete wavelet transform…

In‐plane displacement sensing from circular grating moiré fringes using graphical analysis approach

Researchers in the past have used Fourier transformation method to determine the in‐plane displacement components from moiré fringes generated by a pair of overlapping circular…
