US Classification:

385 12, 356480

Abstract:

An acoustic sensor includes a diaphragm having a reflective element. The sensor has an optical fiber positioned relative to the reflective element such that light emitted from the optical fiber is reflected by the reflective element. A first end of the optical fiber and the reflective element form an optical cavity therebetween. The acoustic sensor further includes a structural element mechanically coupled to the diaphragm and the optical fiber. The structural element includes a material having a coefficient of thermal expansion substantially similar to the coefficient of thermal expansion of the optical fiber. For example, the material can be silica.

International Classification:

G02B 27/01
G02B 1/00
G06F 3/01

Abstract:

A head-mounted display device wearable by a user and supporting a mixed-reality experience includes a see-through display system through which the user can view a physical world and on which virtual images are renderable. At least one light source is configured to emit near infrared (IR) light that illuminates an eye of the user of the near-eye mixed reality display device. An imaging sensor is configured to capture reflections of the near IR light reflected from the eye of the user. A metalens is configured to receive the reflections of the IR light reflected from the eye of the user and direct the reflections onto the image sensor.

Assignee:

International Classification:

G01N 21/64

Abstract:

A camera system includes one or more spectral illuminators, a tunable optical filter, and a sensor array. Active spectral light emitted from the one or more spectral illuminators towards a scene is dynamically tuned to an illumination sub-band selected from a plurality of different illumination sub-bands. Sequentially for each of a plurality of fluorescing light sub-bands different than the selected illumination sub-band, the tunable optical filter is adjusted to block light from being transmitted from the scene to the sensor array in all but a tested fluorescing light sub-band from the plurality of different fluorescing light sub-bands, and the sensor array is addressed to acquire one or more image of the scene in the tested fluorescing light sub-band.

International Classification:

H04N 7/18
H04N 5/247
H04N 5/33
G06K 9/00

Abstract:

A camera system is configured to automatically monitor an area. Depth image(s) of the area are acquired based on active IR light emitted by the camera system and reflected from the area to a sensor array of the camera system. The depth image(s) are computer analyzed to identify a human subject. For each spectral illuminator of the camera system, spectral light image(s) of the area are acquired based on active spectral light in the spectral light sub-band of the spectral illuminator reflected from the area to the sensor array. The spectral light image(s) for the spectral illuminators are computer analyzed to identify an interaction between the human subject and an object in the area. In response to identifying the interaction between the human subject and the object in the area, an action to be performed for the object in the area is computer issued.
