  • Publication number: 20240361589
    Abstract: A two-dimensional scanning micromirror device includes a base, a first platform coupled to the base by first support flexures, and a second platform including a reflector and coupled to the first platform by second support flexures. The first platform is oscillatable about a first axis and the second platform is oscillatable about a second axis orthogonal to the first axis. The first platform, the second platform, and the second support flexures together exhibit a first resonance having a first frequency, the first resonance corresponds to oscillatory motion of at least the first platform, the second platform, and the second support flexures about the first axis. The first platform, the second platform, and the second support flexures together exhibit a second resonance having a second frequency, and the second resonance corresponds to oscillatory motion of at least the second platform about the second axis.

  • Publication number: 20240319790
    Abstract: Techniques are described for enhanced eye tracking for display systems, such as augmented or virtual reality display systems. The display systems may include a light source configured to output light, a moveable diffractive grating configured to reflect light from the light source, the reflected light forming a scan pattern on the eye of the user, and light detectors to detect light reflected from the eye. The orientation of the diffractive grating can be moved such that the light reflected from the diffractive grating is scanned across the eye according to the scan pattern. Light intensity pattern(s) are obtained via the light detectors, with a light intensity pattern representing a light detector signal obtained by detecting light reflected by the eye as the light is scanned across the eye. One or more physiological characteristics and/or a rotation speed of the eye are determined based on detected light intensity pattern(s).

  • Patent number: 12061333
    Abstract: Described are two-dimensional scanning micromirror devices, scanning image display systems that incorporate a two-dimensional scanning micromirror device, and methods of projecting light using two-dimensional scanning micromirror devices. The disclosed two-dimensional scanning micromirror devices can be driven at or near the resonant oscillation frequency of the micromirror structure, which can result in lower power operation. In addition, by driving the micromirror structure at multiple different frequencies, the reflected light can be directed along a non-sinusoidal path, which can improve a tilt angle of the projected light compared with reflected light directed along a sinusoidal path.
