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 maintaining device and a maintenance method for maintaining the normal operation of a resistive random access memory are disclosed. The maintenance method can be executed by the maintaining device. Said memory includes first and second electrodes. The first electrode is not grounded. The maintaining device is connected to the first electrode so that the first electrode receives an operational signal and a restoring signal generated by the maintaining device. The operational signal transits from a zero voltage to a non-zero voltage and then to the zero voltage. If the operational signal has already transited from the non-zero voltage to the zero voltage, the maintenance method controls the restoring signal to transit from the zero voltage to a negative voltage, controls the restoring signal to remain the negative voltage for a period of restoring time, and controls the restoring signal to transit from the negative voltage to the zero voltage.
