Problems solved by technology

[0004] The current mainstream laser light products are still based on static images or combinations of static images that have no internal relationship with each other. Although a few products can display certain dynamic images, the effect is not ideal.

Abstract

The invention discloses a laser animation display method. The display system comprises a laser source, a diffractive optical element and a mechanical driving device. The display method comprises the following steps: S1, first a laser beam whose propagation direction is parallel to a horizontal plane is emitted from the laser source, and the laser beam is incident on a pattern of a first microstructure on the diffractive optical element; S2, the diffractive optical element is driven to be translate by a mechanical driving device so that a laser beam is irradiated on a pattern of a second microstructure of the diffractive optical element, and the patterns on other microstructures on the diffractive optical element are irradiate by the laser beam in turn according to the method; and S3, Continuously moving in cycles to create an animation effect on the terminal screen. The invention realizes the organic combination of the diffractive optical element and the driving device, and realizes the laser animation display on the premise that the motion control unit is not additionally added and the system volume and the cost are hardly increased. The method is low in cost, and easy to popularize.

Description

technical field [0001] The invention relates to an animation display method, in particular to a laser animation display method. Background technique [0002] The laser lamp is mainly composed of three parts: laser light source, mechanical movement device and diffractive optical element. The surface of the diffractive optical element is processed with micro-nano-scale steps. Using the diffraction effect of the steps on light, the diffractive optical element can output the incident point-shaped laser as the required image. Due to the high brightness and high collimation characteristics of the laser, the laser light can realize long-distance and high-brightness image display, so it has developed rapidly in the European, American and domestic markets in recent years. [0003] Although laser lights have a history of more than 10 years, most laser light products on the market can only display static images. In order to enrich the performance content and improve the performance e...
