In June, 8 members of the Engineering Photonics team attended the Laser World of Photonics trade show in Munich. This is one of the world’s largest trade shows for optics and photonics and is held biennially at Messe München to the east of the city. This year there were nearly 1,300 exhibitors and more than …

A recent paper, published in the IOP journal Measurement science and technology describes the application of infinity corrected lenses, commonly used for microscope objectives, for full-field interferometry applications such as optical flow measurement and speckle interferometry. The paper “Full-field interferometry using infinity corrected optics” describes critical considerations for constructing path-length imbalanced full-field interferometers using such …

Our research on electronic speckle pattern interferometry (ESPI) was recently published in Measurement Science and Technology. Our interferometer uses a simple and compact optical arrangement which acquires a reference wave from a wedged window placed in the path of the illuminating beam. The design has come out of our work investigating the effects of laser speckle in …

Recently we published a paper in Applied Physics B describing our research into the propagation of mid-infrared laser light through hollow silica waveguides. The laser that we were using is a mid-infrared (7.8 μm) quantum cascade laser that is housed in a research platform based on a Cascade Technologies laser spectroscopy system. Hollow silica waveguides are narrow tubes made …
