Applications Of Raman Spectroscopy In Explosives Detection

At present, with the continuous occurrence of various terrorist incidents, safety and security work has received more and more attention. There are many kinds of explosives and various hidden means. The inspection work is very difficult, so, the timely and effective detection of explosives that have been camouflaged and hidden in the baggage has become an urgent and arduous task in the world.Common explosive detection methods include: ion mobility spectroscopy, ultraviolet fluorescence, mass spectrometry, nuclear magnetic resonance, neutron technology, X-ray imaging, γ-ray imaging, etc., but each method has some advantages and disadvantages. Raman spectroscopy can realize the remote, high-sensitivity, non-damage and micro-trace detection of explosives, and has a huge application market in the field of explosives.In this article, Raman spectroscopy technology is applied to the field of explosives detection, focusing on the application of confocal Raman microscopy, surface-enhanced Raman...

The application field continues to expand. The fiber laser market has broad prospects.

The emerging fiber laser technology market is expected to make significant progress in the sensing and medical fields, and the innovation in laser welding and 3D printing technology means that material processing remains the main market focus in the medium term.Market research firm IDTechEx said: ' Market research firm IDTechEx said: 'The fiber laser is a compact, energy-efficient laser system that provides the best beam quality for applications where accuracy is critical. Because the technology is based on optical fiber, there are no free-space optical and mechanical components, that provide excellent system stability and long product life. Directing the laser radiation through the fiber to the application point ensures safe operation of the human body and simplifies integration with the machine. ”As a result, fiber lasers can be used to replace traditional laser or non-laser technologies in a variety of industries to maximize processing speed and accuracy while minimizing ope...

Why Laser Light Source Will Be the Future Direction

Nowadays, more and more home appliance manufacturers are beginning to move closer to the laser TV product line. With the deepening of a series of brands, laser projections have gradually gained the attention of the consumer groups. For families who love movies and have ample family space, building a home theater is no longer a dream. Looking at the projector market, we can find that the light source is mainly divided into three categories, namely the bulb light source, the LED light source and the laser light source. What are the differences between the three types of light sources? Why do most people in the industry regard laser projection as a future product for projectors? Let us analyze it together.Throughout the market, we can find that different forms of light sources have been developed in different fields. For example, traditional bulb sources are currently widely used, and the market share is still large. They occupy a large share in the commercial and household fields. Laser ...

The development of fiber technology has realized the wide application of fiber laser equipment.

The development of optical fiber technology has enabled the widespread use of fiber laser equipment in large-scale production in many market segments.Automation is expected to drive laser welding in markets such as automobiles.Car engines convert gasoline into power, but its split fire cover moves the vehicle by transmitting high voltage from the ignition coil to the spark plug. The traditional split fire cover has been given to the electronic ignition system, which is followed by the latest developments of the car manufacturers – the fire-free ignition system.Thanks to the advancement of optical fiber technology, fiber lasers have achieved significant growth. In the past decade, the rapid industrialization and adoption of fiber lasers has been largely attributed to the physicist Valentin Gapontsev, who led the development of optical fiber technology.“My dream is to see lasers like computers, becoming a tool of choice in mass production, rather than being considered a last resort choic...
