A headset includes an optical assembly, an adjustment assembly, and a measurement component. The measurement component is configured to measure an interpupillary distance provided by an adjustment assembly in a first direction and an eye relief distance provided by the adjustment assembly in a second direction, where the first direction is orthogonal to the second direction. The measurement component includes a first rheostat configured to measure the interpupillary distance and a second rheostat configured to measure the eye relief distance, wherein the second rheostat is placed parallel to the first rheostat. The measurement component further includes a linkage configured to translate a motion of the adjustment assembly in the second direction to the first direction.

Adjusting interpupillary distance and eye relief distance of a headset

A headset includes a housing, an optical assembly disposed in the housing, and an adjustment assembly coupling the optical assembly to the housing. The optical assembly includes a first lens and a second lens spaced from the first lens by a first distance. The adjustment assembly includes an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism. The interpupillary distance adjustment mechanism is configured to adjust the first distance between the first lens and the second lens along a first axis. The eye relief distance adjustment mechanism configured to adjust the optical assembly a second distance along a second axis orthogonal to the first axis.

The disclosed system for varifocal adjustments may include a frame, an optical lens pair supported by the frame, and a brake mechanism coupled to the frame. The optical lens pair may include a first lens that is movably coupled to the frame and a second lens that is fixedly coupled to the frame. The brake mechanism may be configured to frictionally stop movement of the first lens and to maintain a position of the first lens. Various other devices, systems, and methods are also disclosed.

Systems and methods for varifocal adjustment brakes

The disclosed systems for varifocal adjustments may include a frame, an optical lens pair supported by the frame, and a flexure assembly. The optical lens pair may include a first lens that is movably coupled to the frame and a second lens that is fixedly coupled to the frame. The flexure assembly may be configured to constrain movement of the first lens to a substantially linear pathway. The flexure assembly may include at least one substantially planar flexure element having a first movable end portion coupled to the first lens and a second fixed end portion coupled to the frame. Various other devices, systems, and methods are also disclosed.

Systems and methods for varifocal adjustments

A varifocal head mounted display (HMD) includes an electronic display, an optical system, and the guidance system. The electronic display presents content. The optical system includes one or more optical elements and provides the content to an eyebox of the HMD. The guidance system is a flexure based guidance system that includes an actuator and a first and second flexure elements (e.g., parallel beam, dual Roberts, etc.) guiding movement of the electronic display along an optical axis of the optical system in order to adjust a location of one or moveable elements in the optical system and, thereby, control a location of an image plane. The first and second flexure elements are able to flex or bend with movement of the actuator to adjust the location of the one or moveable elements that includes the electronic display and/or one or more optical elements of the optical system.

Flexure based guidance system for varifocal head-mounted displays

A shutter for an optical system, such as a small infrared camera, for alternately blocking and exposing an optical sensor to light includes an electrically conductive coil, having a center long axis, a magnet element rotatably mounted within the coil with an axis of rotation perpendicular to the center long axis of the coil, a shutter flag element connected to the magnet element, and a shutter base element supporting the shutter flag, magnet, and coil. Energizing the coil in a first manner causes the rotatable magnet to rotate from a first position to a second position and energizing the coil in a second manner returns the magnet to the first position, causing the flag to alternately block and expose the optical sensor.
