Beam profiling systems are an essential technology to ensure the quality and uniformity of lasers. Beam profilers measure the optical spatial intensity of an input laser beam,  providing information about ...

Work with Mirrors in Advanced Scientific Disciplines Many times when people think of mirrors they fail to think about their advanced scientific applications. However, telescopes and other devices contain ...

Optical myography is a technique that visually inspects the human forearm to determine the hand posture. Hand posture is a communication element as important as the language itself. Human hand gesture ...

The millimeter-wave (MMW) region of the electromagnetic spectrum is a region of frequency band between 30 gigahertz and 300 gigahertz, and it is called the Extremely High Frequency range. These high ...

High power lasers are used in the industry routinely for cutting, drilling, welding and micromachining materials. They have also found applications in medicine where tissue needs to be cut or heated. The ...

X-Rays and Imaging We commonly associate x-ray imaging with hospitals and broken bones, but why are x-rays the chosen source of radiation instead of visible light or electron beams? The high initial energy ...

Researchers from Tsinghua University in Beijing, China, recently published their findings on using the Monte Carlo method during the design of skin-like optical devices. The Monte Carlo method allows for ...

In 1963, Leon Goldman became the first person to report using lasers in dermatology. Goldman reported the effects of Ruby laser in the selective destruction of cutaneous pigmented structures, like black ...

Tissue welding is a relatively new procedure that aims to seal wounds and openings in a surgery using laser. The first tissue welding application using lasers was done in 1964 to join small blood vessels ...

A research team at Keio University in Japan devised a novel handheld viscosity sensor capable of quick, non-contact in situ measurements. Viscosity is a fundamental property for liquid analysis in a wide ...
