    Abstract: The disclosure provides a driving apparatus, a driving method thereof, and a scanning mirror. The scanning mirror includes an accumulator unit and a processor unit. The accumulator unit receives and adds up a frequency control word and a first accumulation value to generate a second accumulation value. The processor unit coupled to the accumulator unit receives the second accumulation value. The processor unit generates a driving signal according the second accumulation value and the preset value and adjusts the second accumulation value for outputting the first accumulation value.

    Abstract: An optical scanning projection module includes a scanning light component including a plurality of sub light sources and at least one light-splitting element, a main light reflective element, a scanning element and a photosensitive element. Sub light beams of the sub light sources are converged to form a main light beam. One of the sub light beams travels to the light-delivering element to form a partial reflective light beam and a partial penetrating light beam. With a scanning manner, the partial reflective light beam or the partial penetrating light beam is reflected by the scanning element to be an inspection light, and the main light beam is reflected by the scanning element to be a projection light. The photosensitive element outputs a sensing signal according to the inspection light. Thus, the optical scanning projection module controls the operation of the scanning light component according to the sensing signal.

    Abstract: Disclosed herein are a Lissajous dual-axial scan component and a scan frequency generation method thereof. The Lissajous dual-axial scan component scans at a fast-axial resonant frequency and a slow-axial resonant frequency. A fast-axial bias frequency and a slow-axial bias frequency are determined according to the fast-axial resonant frequency and the slow-axial resonant frequency. Fast-axial positive integers and slow-axial positive integers are determined according to a system frequency, the fast-axial bias frequency, and the slow-axial bias frequency. An irreducible fraction is determined according to the fast-axial positive integers and the slow-axial positive integers as a ratio of the fast-axial bias frequency to the slow-axial bias frequency less than 10. A scan trace repetition frequency greater than 24 Hz is determined according to the irreducible fraction in order that the Lissajous dual-axial scan component scans according to the scan trace repetition frequency.
