WebJun 1, 2024 · Unique optical parameters that enable imaging systems to capture the full visible FOV include the lens aperture position and geometry. In an optical system, such as the lens on a camera, the aperture or “entrance pupil” is the initial plane where light is received into the lens. A similar point exists in the pupil of the human eye. WebNov 11, 2024 · FoV is determined by the camera lens and sensor size. The human eye has an average field of view of about 170-180 degrees. In photography, you can change the …

WebJun 18, 2024 · The optical waveguide can be generally categorized into geometric type and diffractive type. The geometric waveguide is the so-called “ array waveguide ”, which expands the eyebox in one dimension through an array of transflective mirrors. The pioneering optical company for geometric waveguide is Lumus.
