Abstract: The training method for the phase image generator includes the following steps. Firstly, in each iteration, a loss value is generated, including: (1). the phase image generator generates a plurality of generated phase images using a phase image generation mode; (2). the phase image determiner determines a degree of difference between the generated phase images and original phase images; (3). the loss value of the generated phase images is generated according to the degree of difference. Then, a selector selects a stable loss value from the loss values, and uses the phase image generation mode in the iteration corresponding to the stable loss value as a selected phase image generation mode of the phase image generator.

Abstract: A camera array apparatus including a plurality of cameras and a light deflection module is provided. The cameras are arranged in an array. The light deflection module is disposed on the cameras. The light deflection module includes at least one prism set. The prism set has a plurality of prisms. The prism set is configured to deflect a light entering obliquely with respect to an optical axis of the cameras to at least a portion of the cameras. The angle between the optical axis and the deflected light is smaller than the angle between the optical axis and the light before being deflected.

Abstract: A surface processing equipment using an energy beam including a measuring device, a gas source, an energy beam supply device, a multi-axis platform, and a processing device is provided. The measuring device measures a workpiece to obtain surface form information. The energy beam supply device receives a processing gas to form an energy beam. The energy beam supply device includes a rotating sleeve. Openings are on a bottom surface of the rotating sleeve. The rotating sleeve rotates along a rotation axis and supplies the energy beam from one of the openings to the workpiece. The processing device controls the gas source, the energy beam supply device, and the multi-axis platform according to the surface form information. Distances from each opening to the rotation axis are all different. The energy beam is formed into a beam shape or rings having different radii via a rotation of the energy beam supply device.

Abstract: A head-up display with variable focal length includes a projector which provides a beam with image, a magnifier lens module which is disposed on the route of the beam, and an array of lens which is movably disposed between the projector and the magnifier lens module. The beam forms an inter-image after passing the array of lens, then forms a virtual image after passing the magnifier lens module. To change the position of the virtual image, adjust the relative position between the array of lens and the magnifier lens module. A dispersion angle of the array of lens is θd, a magnification of the magnifier lens module is M, a distance between the virtual image and user's eyes is VID, a visible range of user's eyes is Et, and satisfies the relationship as following: θd=M*2*cot−1 (2VID/Et).
