摘要： The present invention provides a method for assembling a camera module, including: arranging a first sub-lens assembly and a photosensitive assembly on an optical axis of a second sub-lens assembly to form an optical system capable of imaging; increasing an actual measured resolution of imaging of the optical system to a first threshold by adjusting a relative position of the first sub-lens assembly with respect to the second sub-lens assembly; decreasing an actual measured image plane inclination of imaging of the optical system, obtained by using the photosensitive element, to a second threshold by adjusting an angle of an axis of the photosensitive assembly with respect to a central axis of the second sub-lens assembly; and connecting the first sub-lens assembly, the second sub-lens assembly, and the photosensitive assembly. The present invention further provides a corresponding camera module. The present invention can improve the resolution of the camera module; can improve the capability of process index of mass production of the camera module; can reduce the overall costs of the optical imaging lens assembly and module; and can reduce the failure rate and the production costs, and improve the imaging quality.

摘要： An augmented reality display device (100), comprising: a light engine (102) for emitting image light; and at least one layer of optical waveguide lens (101) comprising an in-coupling grating region (1012), an optical waveguide substrate (1011) and a turning and out-coupling grating region (1013), wherein the in-coupling grating region (1012) is disposed on a first optical surface of the optical waveguide substrate (1011); the optical waveguide substrate (1011) is configured to transmit the image light through total reflection; the turning and out-coupling grating region (1013) is disposed on the first optical surface of the optical waveguide substrate (1011) for receiving totally reflected light and coupling it out; and a sum of the in-coupling grating vector and the turning and out-coupling grating vectors is not zero, wherein the in-coupling angles of the light engine (102) and the respective layers of optical waveguide lenses (101) are identical. As a result, the light engine (102) and the optical waveguide lenses (101), even in the case of non-perpendicular in-coupling, can ensure that the central field of view of the light engine (102) coincides with the central field of view of human eyes, greatly improving the degree of freedom of the structural design of the light engine (102) and the optical waveguide lenses (101), so that the structure of the augmented reality display device (100) is diversified, and the display device is manufactured as having a smaller size.
