 In recent years, interactive display systems and products represented by multi-touch and interactive projection have developed rapidly. This kind of intuitive, easy-to-use, and novel interactive experience has gradually changed the public's usage habits and has become a new type of application with important industrial significance and commercial value. Interactive projection mainly uses infrared sensor capture equipment to capture and shoot participants, and then analyzes through the internal imaging system, and generates feedback actions corresponding to the captured information during actual content. Combined with the real-time image interactive system, participants can interact with the wall To interact effectively with the body screen. The infrared surface emitted by the infrared line laser covers the entire screen. The thickness of the infrared surface of the laser is about 2mm. When the finger or other objects are close to the touch screen, the infrared surface of the lase...

Sébastien Février, researcher at XLIM (CNRS/Université de Limoges), and his team demonstrated that a bench-top, optical fibre-based laser source can be used to perform infrared spectromicroscopy with a precision rivaling, and in some regards even surpassing, that of experiments at large-scale synchrotron facilities. Synchrotrons are accelerator facilities that provide powerful infrared light used for analyzing the chemical content of biological tissues with micrometer scale resolution. This high precision chemical imaging technique enables an early diagnosis of pathologies such as cirrhosis and cancer. However, up to now, the very high cost of ownership and limited availability of synchrotron sources has hindered the deployment of chemical imaging technique in the hospital. Replacing the synchrotron with a compact laser source could unleash the potential of this technique and ease its implementation in the hospital, thus accelerating access to diagnosis and treatment. The res...

High-power ultrafast pulsed lasers are used widely for biomedical applications and imaging, materials processing, industrial micromachining and more. But many laser-eyewear products are not tested with ultrafast lasers and may not be providing adequate protection for the technical workers who depend on them. The main reason for this situation lies in the typical test procedures and standard measurements widely followed by eyewear makers to set their product specifications. Those methods use low-power continuous-wave (CW) light sources. As a result, they do not capture many potential hazards of actual high-power , pulsed-laser working conditions. Moreover, end users only infrequently test how their eyewear performs in particular applications prior to deployment. Scientists at the National Institute of Standards and Technology (NIST; Gaithersburg, MD and Boulder, CO) and Hood College (Frederick, MD) have published a study of 24 samples of protective filters used in eyewear from fiv...
