Abstract: In systems and methods for adjusting the position of a headset element (e.g., a display and/or other optical element), coherent light (e.g., a laser beam) is transmitted through a display of a headset to produce a diffraction pattern on a detector, which detects the diffraction pattern. The orientation of the headset element is determined based in part on the detected diffraction pattern. Based on the determined orientation and a target orientation, an adjustment to the orientation of the headset element is determined. The position of the headset element is adjusted based on the determined adjustment. This method may be repeated until the headset element is determined to be correctly oriented.

Manipulation of the nanovoid topology, such as through capacitive actuation, can be used to reversibly control the effective refractive index of the nanovoided polymer and hence the grating efficiency.

Abstract: A driver for powering a pulsed light source of a scanning projector display is configured to provide a succession of powering electric pulses to the light source. Duration of the powering electric pulses is less than a pixel time interval during which a scanner of the projector display is directing the light beam to form a corresponding pixel of the image to be displayed. The amplitude of the powering electric pulses is proportionally higher, such that the light pulse has a pulse energy similar to the light energy provided by the light source when continuously driven through the pixel time interval. This enables the light source to be operated at a steeper portion of the electro-optical transfer curve, thereby improving the wall plug efficiency of the scanning projector display.

Abstract: In some examples, a virtual surface presented by an artificial reality (AR) system may be a virtual drawing surface in an artificial reality environment, with which users may interact using a physical peripheral device. For example, the AR system may enable a user to draw or write on a surface of the peripheral device and may simultaneously, i.e., along with the user inputs, render virtual markings corresponding to the user inputs on a virtual drawing surface locked to the surface of the peripheral device. In some cases, the AR system enables the user to “transfer” the virtual markings rendered on the surface of the peripheral device (e.g., a virtual drawing) to another virtual drawing surface (e.g., to a planar or other surface in the artificial reality environment).
