Abstract: A laser inspection system is provided. A laser source emits a laser with a first spectrum and the laser is transmitted by a first optical fiber. A gain optical fiber doped with special ions is connected to the first optical fiber, and a light detector is provided around the gain optical fiber. When the laser with the first spectrum passes through the gain optical fiber, the gain optical fiber absorbs part of the energy level of the laser with the first spectrum, so that the laser with the first spectrum is converted to generate light with a second spectrum based on the frequency conversion phenomenon. The light detector detects the intensity of the light with the second spectrum, so that the power of the laser source can be obtained.

Abstract: A user interface synchronous scrolling method includes: opening a plurality of user interfaces, obtaining a scrolling parameter through the input-output interface; and judging whether the application program corresponding to each user interface belongs to a software support mode. By determining whether the application program corresponding to each user interface belongs to the software support mode, and providing corresponding control steps, the effect of synchronous scrolling for multiple user interfaces is achieved.

Abstract: A supporter is provided, and includes a base, a holder, and a linkage assembly. The base has a surface and a groove that is formed on the surface. The holder is disposed on the surface of the base. The linkage assembly is disposed in the base. The linkage assembly is rotatable relative to the base. The linkage assembly includes a first shaft, a second shaft, and a linkage member. The first shaft is at least partially disposed in the groove. The second shaft is connected to the holder. The linkage member is connected to the first shaft and the second shaft. The linkage member is configured to link the first shaft to the second shaft.
