摘要:
Audio systems and methods are provided that include an acoustic driver and an optical light source, each coupled to a head-worn structure. The acoustic driver is configured to convert an audio signal into an acoustic signal in proximity to an ear of the user. The optical light source is configured to direct optical energy toward an eye of the user. A user interface coupled to the light source is configured to control at least one of a color selection, a luminance, or duration of the optical energy.

A method and system for spot size selection wherein an indication of a spot size selection is received and a spot size is generated corresponding to the spot size selection by propagating an optical signal via one of the claddings of a dual-clad optical fiber. The system for spot size selection includes a plurality of lens arrays, at least one galvanometer, and a plurality of dual-clad fibers to propagate an optical signal from one of the plurality of lens arrays.

Die Erfindung betrifft eine ein Fixierlicht aussendende Vorrichtung, wobei das Fixierlicht von einem Beobachterauge angepeilt werden kann, um die Blickrichtung des Auges zu fixieren. Die Fixierlicht-Vorrichtung umfasst ein Hohlzylinder-Axicon mit einer optischen Achse, eine Punktlichtquelle für sichtbares Licht, wobei die Punktlichtquelle auf der optischen Achse vor dem Hohlzylinder-Axicon angeordnet ist, eine Linse, die auf der optischen Achse hinter dem Hohlzylinder-Axicon angeordnet ist, und eine Kernlichtblende, die zwischen der Punktlichtquelle und dem Hohlzylinder-Axicon angeordnet ist. Die Anordnung der Punktlichtquelle und des Hohlzylinder- Axicons bestimmt die Lage einer Fokusstrecke, und ein Punkt aus dem Mittenbereich der Fokusstrecke liegt in der vorderen Brennebene der Linse.

A pupil tracking system including a light source for illuminating a viewer's eye, an aperture located to pass light from the light source after retro-reflection from the viewer's pupil, the aperture sized and shaped to pass the light from the light source and block at least a portion of other light arriving at the aperture, and a light sensor for tracking a location of a spot produced by the light from the light source which passed the aperture. Related apparatus and methods are also described.

An instalment for imaging the eye and performing ophthalmic diagnostic tests is disclosed that obtain images of the stractures of the eye using imaging technology such as optical coherence tomography (OCT). To assist with such imaging and/or provide additional diagnostics, the ophthalmic diagnostic instrument may additionally include a display for presenting images to the subject whose eyes and vision are being evaluated. This display system, may comprise a MEMS (microelectromechanical system) scanning mirror.

Methods and systems for performing an ophthalmic surgical procedure include pulsed illumination of target tissue. The systems may include an illumination instrument arranged to illuminate tissue at a surgical site during the ophthalmic surgical procedure. A light source provides illumination to the illumination instrument for emission from the illumination instrument toward the surgical site. A controller communicates with the light source and activates the light source to provide illumination pulses at a frequency above the flickering perception in humans and with enough light for cameral exposure and human light perception. The light source pulses to minimize phototoxicity.

The present invention discloses an apparatus and a method for adaptive illumination, the system comprising, one or more light sources to emit light beams of multiple wavelengths, a time multiplexing module to produce a time multiplexed beams from the emitted light beams, a light beams combiner to produce collimated light beams from the time multiplexed beam and a processor, to operate a spatial light modulator configured in the apparatus to produce spatial pattern of predefined intensity of a subject. Further, the collimated light beam is spatially modulated to adaptively illuminate the subject.
摘要:
Apparatus and methods for producing narrow-band radiation in the green region of visible spectrum are described. The narrow-band radiation may be used to aid subjects experiencing photophobia. In some cases, subjects may experience a reduction in pain (e.g., migraine photophobia) when using the narrow-band radiation.
