From the development of efficient quantum cascade lasers that cover most of the mid-infrared region to excimer lasers that provide a range of different UV wavelengths, advances in laser technologies mean that most applications can now make use of an appropriate laser source.

Quantum theory is used in a variety of microscopy techniques. Quantum microscopy enables the measurement and imaging of tiny features of matter and quantum particles. This article provides an overview of how quantum microscopy can drive the future of sensing and imaging.
Fiber optic microendoscopes have become invaluable imaging tools that have enabled endoscopists to see and describe previously inconceivable things. This article will look into their history, applications, recent research and developments, challenges, and future industry prospects.
A special diagnostic tool for determining the physical conditions in the interstellar medium of galaxies is provided by mid-infrared spectra.

A new fabrication method for quantum dots could lead to more effective and efficient quantum dot displays, especially due to improvements in the generation of blue-colored quantum dots. The process has been called a “bottom-up, self-organizing chemistry” by its designer, Dr. Eiichi Nakamura of Tokyo University.

One of the most challenging aspects of developing self-driving cars, particularly for vehicles that will be used in environments with mixed autonomous and manually operated vehicles, is developing sensor systems that can deal with the range of distances, weather, and light conditions that the vehicle will be exposed to.

Photoelectron spectroscopy involves the detection of the kinetic energies of photoelectrons emitted following an ionization event. If it is assumed that the emitted photoelectrons do not undergo any collisional event post-ionization, the kinetic energy of the detected electron should be equal to the binding energy of the orbital it was ejected from.

Mass spectrometry is an analytical technique used for chemical identification. By ionizing and fragmenting the sample of interest and measuring the mass-to-charge ratios of the products formed, it is possible to see a ‘chemical fingerprint’ that can help work out a chemical structure. Mass spectrometry can also be used to identify unknown compounds.

Diffuse reflectance spectroscopy is a type of absorption spectroscopy where, rather than measuring the transmitted beam through the sample, the light reflected from the sample is measured instead. It is a common method for measuring opaque samples that absorb too strongly to be measured in transmission.
