Paper Abstract

In this paper, we design a setting that could constantly monitor the screen vibration frequency and a speckle measurement system that simulates characteristics of human eye to record speckle images. Three vibrating methods, including acoustic wave vibration, frame vibration and chip motor vibration, are adopted to eliminate speckle. Speckle contrast, power consumption and noise are measured, separately. On our experimental platform, when the speckle contrast is less than 5%, the human eyes perceive free of speckle. By comparison, the chip motor vibration has optimal performance that the speckle contrast is 4.97%, power consumption is 1.51 W, and noise is 43.1 dBA. Therefore, the chip motor vibration method is the most suitable method for improving image quality in laser display.
