    Principle of laser gas detection
    TDLAS technology is essentially a spectral absorption technology. The concentration of gas can be obtained by analyzing the selective absorption of laser by gas. It differs from traditional infrared absorption technology in that the spectral width of semiconductor lasers is much smaller than that of gas absorption lines.

  • Measurement of narrow linewidth for laser diode
    Measurement of narrow linewidth for laser diode
    Although both spectrum and spectrum are electromagnetic spectra, the analysis methods and testing instruments of spectrum and spectrum are quite different because of the difference of frequency. Some problems are difficult to solve in the optical domain, but it is easier to solve them by frequency conversion to the electrical domain.

    LAN and plastic fiber media
    Local Area Network (LAN) refers to a group of computers interconnected by multiple computers and other devices in a certain area. They are physically apart from each other to allow users to communicate with each other and share such as printers and storage. A system in which computing resources such as devices are interconnected.

  • Optical fiber sensor network structure
    Optical fiber sensor network structure
    Fiber optic sensor networks have three basic components, one of which is called a single point sensor. One fiber only serves as a transmission here, and the other is a multi-point sensor, where a fiber bundles many sensors so that many sensors can share the light source for network monitoring. Then there is the smart fiber sensor. The multi-point fiber optic sensor is a grating...

  • The role of the optical module in the data center
    The role of the optical module in the data center
    In the data center, optical modules exist everywhere, but few mention them. In fact, optical modules are already the most widely used products in the data center. Today‘s data centers are basically fiber-optic interconnections, and the number of cable interconnections has become less and less, so there is no optical module, and there is no way for the data center to operate. T...
