Abstract:
The present invention discloses a laser animation display method. A display system includes three parts, i.e., a laser source, a diffraction optical element and a mechanical driving device. The display method includes the following steps: S1: the laser source emits laser at first, and the laser is caused to be incident on the pattern of a first microstructure on the diffraction optical element; S2: the diffraction optical element is driven by the mechanical driving device to translate to irradiate the pattern of a second microstructure of the diffraction optical element with the laser, and the patterns on other microstructures are sequentially irradiated with the laser according to the same method; and S3: cyclic movement is kept, thereby achieving an animation effect on a screen. The present invention implements laser animation display on the premise of no additional motion control unit and almost no increase of the system size and cost.

Claim (Index 1):
A laser animation display method of a display system (DS) which comprises laser source (L) which emits a laser lamp light ( 5 ), a mechanical driving device (M) and a diffraction optical element (OE) arranged on the mechanical driving device (M), wherein a plurality of microstructures (O 1 , O 2 , O 3 , O 4 ) are arranged on the diffraction optical element (OE), and the diffraction optical element (OE) is driven by the mechanical driving device (M) to perform relative translation motion relative to the laser lamp light ( 5 ) emitted by the laser source (L);\n the laser animation display method comprises the following steps: S1: emitting the laser lamp light ( 5 ), and causing the laser lamp light ( 5 ) to irradiate on a first microstructure (O 1 ) arranged on the diffraction optical element (OE) which is placed perpendicular to a plane in a propagation direction of the laser lamp light ( 5 ), such that the laser lamp light ( 5 ) projects a static image on a screen (B); S2: driving the diffraction optical element (OE) by the mechanical driving device (M) to translate and change its position relative to the laser lamp light ( 5 ) in a plane in which the diffraction optical element (OE) is located so as to cause the laser lamp light ( 5 ) to irradiate on a second microstructure (O 2 ) arranged on the diffraction optical element (OE), so as to change the static image formed by the laser lamp light ( 5 ) in Step S1, and sequentially irradiating on other microstructures (O 3 , O 4 ) arranged on the diffraction optical element (OE) with the laser lamp light ( 5 ) in the same manner; and S3: repeating Step S2, and keeping cyclically moving the diffraction optical element (OE) driven by the mechanical driving device (M), thereby displaying dynamic images the screen (B).
