    Abstract: A method for preparing a large-area catalyst electrode includes the following steps: (A) providing an iron compound, a cobalt compound and a nickel compound, and dissolving these metal compounds in a solvent to form a mixed metal compound solution, and (B) providing a cathode and an anode, and performing a cathodic electrochemical deposition to the cathode, the anode and the mixed metal compound solution in a condition of constant voltage or constant current through a two-electrode method, followed by obtaining a catalyst electrode from the cathode. In the method for preparing the large-area catalyst electrode of the present invention, the large-area catalyst electrode having good dual-function water electrolysis catalytic property can be prepared by the steps of preparing the electrolyte, the electrochemical deposition, and the like. The process is simple and energy-saving.

    Abstract: A light detection and ranging system comprises an optical transmitter for beam scanning on a scan region, and receiving reflected light from the scan region; and an optical receiver for directing the reflected light for signal conversion. The optical transmitter includes a beam refractive unit including optical refractive devices, rotatably disposed about a rotation axis, for directing a collimated laser beam from a first optical path towards a direction depending on rotation angles of the optical refractive devices; and a motion unit for actuating relative motion of the optical refractive devices so as to perform beam scanning towards directions on the scan region. The optical receiver includes an off-axis reflective unit, disposed in the first optical path, for directing the reflected light towards a second optical path; and a light detection unit, disposed in the second optical path, for performing signal conversion on the reflected light.
