Beam Profiling Systems and Their Applications
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 ...
Mirrors and the James Webb Space Telescope: Probing the Origins of the Universe
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: Detecting Hand Posture by Looking at Forearm
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 ...
Innovative Electric Components for Millimeter Wave Communication
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 ...
Diode Laser Array: Delivering High Power Outputs by Combining Stacks
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 ...
Computational Ghost Imaging: An Unconventional Solution
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 ...
Skin-Like Device Design Using the Monte Carlo Method
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 ...
Laser Tissue Interactions: Biological Factors to Consider for Dermatology
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 Using Lasers for Sutureless Surgical Procedures
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 Novel Handheld Viscosity Sensor for Medical and Industrial Applications
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 ...
