【Abstract】 This paper analyses the necessity to take the visual angle as the standard of quality in 2D/3D and 3D rainbow hologram and gives the reason of choosing the laser beam as the illuminating light while measuring the visual angle. The paper also describes the relation between the visual angle of object and the visual angle of image. The detail method to measure the visual angle is also presented.更多还原
