    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.

    Abstract: A projector device is provided. The projector device includes a projector unit, an optical beam splitting module and a first image forming element. The projector unit forms a beam projecting image. The horizontal projection width of the beam projecting image is smaller than the vertical projection width of the beam projecting image. The optical beam splitting module projects one or multiple projection sub-images according to the beam projecting image. The projection sub-images are projected to the first image forming element to form one or multiple projection images. Thus, the projector device obtains multiple projection images from a single image source, and the placement of the image forming elements in the projector unit may be adjusted to obtain the projection images with the best image ratios and the best resolutions. The projector device may be suitable for a head up display.

    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.
