摘要： A method for assembling a first lens and a second lens is provided. The method includes performing an optical center measurement for at least one of the first lens or the second lens, and performing an optical center adjustment when the optical center measurement does not satisfy a predetermined optical center condition. The method also includes performing a polarimetric measurement for at least one of the first lens or the second lens, and performing a polarimetric angle adjustment when the polarimetric measurement does not satisfy a predetermined polarimetric condition. The method further includes assembling the first lens and the second lens to form an optical assembly.

摘要： The disclosed system may include (1) a lens assembly that provides an electronically controllable cylindrical power, oriented along an electronically controllable axis, on an optical path between a display device and an eye of a viewer in response to at least one first control signal, and (2) a controller that (a) receives information indicating a cylindrical power component and a cylindrical axis component of an eyeglass prescription for the viewer, and (b) generates, based on the information, the at least one first control signal to cause the lens assembly to provide the cylindrical power component, oriented along the cylindrical axis component, for the viewer. Various other systems and methods are also disclosed.

摘要： A method for calibrating includes obtaining a head-mounted display device that includes an electronic display having an array of display elements and an array of beam steerers located over an inner left portion and an inner right portion of the electronic display. The method also includes obtaining alignment information by selecting a first respective subset of the array of display elements and causing it to emit light, and determining whether the light is received by a first optical sensor in a first position or a second optical sensor in a second position, thereby determining whether the first respective subset of the array of display elements is aligned for the first or the second optical sensor. The method also includes repeating the selecting, causing, and determining operations for a second subset of the array of display elements, and storing the alignment information for calibrating images for presentation by the electronic display.

摘要： The disclosed method may include (1) providing, from a display, an image to an eye by way of a lens assembly on an optical path between the display and the eye, wherein the lens assembly includes (a) a first liquid crystal lens providing a first electronically controllable cylindrical power, oriented along a first constant axis, in response to a first signal and (b) a second liquid crystal lens providing a second electronically controllable cylindrical power, oriented along a second constant axis that is rotationally offset from the first constant axis, in response to a second signal, (2) determining, based on information indicating cylindrical power and cylindrical axis components, the electronically controllable cylindrical powers that result in providing the cylindrical power component, oriented along the cylindrical axis component, and (3) generating, based on the electronically controllable cylindrical powers, the signals. Various other systems and methods are also disclosed.

摘要： An optical characterization system tests optical elements of head-mounted displays (HMD) such as lenses. The system emits a test pattern of light through an aperture of a hollow truncated cone. The hollow truncated cone may be rotated to different angles of test positions, for example, to mimic rotation of a human eye of a user wearing an HMD. The emitted light is refracted by a test lens and captured by a detector assembly. Using images captured by the detector assembly, the system determines one or more quality metrics of the test lens. Quality metrics may describe various types of optical aberrations, which may be determined as a function of the test positions (e.g., angle and/or position of the hollow truncated cone relative to the test lens). In addition, the system may generate an optical profile of the test lens using the quality metrics.
