An integrated circuit is configured for optical communication via an optical polymer stack located on top of the integrated circuit. The optical polymer stack may include one or more electro-optic polymer devices including an electro-optic polymer. The electro-optic polymer may include a host polymer and a second order nonlinear chromomophore, the host polymer and the chromophore both including aryl groups configured to interact with one another to provide enhanced thermal and/or temporal stability.

Techniques are generally described for detecting a concentration level of at least one gas. Some example devices may include a sensor including conductive plate on a surface of dielectric including a nanotube layer formed thereon. The conductive plate and the nanotube layer form a resonator that resonates at a frequency in response to an interrogation signal. The nanotube layer may be configured to associate with one or more gas molecules. The frequency at which the resonator resonates may shift according to which gas molecules are associated with the nanotube layer to identify a particular gas. An amount of resonance may be exhibited as a resonant response signal. An amplitude of the resonant response signal may be indicative of the concentration level of the detected gas.

Energy storage devices for storing energy are provided. An energy storage device includes a flywheel disposed in a chamber of a journal. A gas bearing is formed between an outer face of the flywheel and an inner face of the journal. The gas bearing exerts a compressive force on the flywheel, which allows for higher rotational velocities and higher energy storage.

A scanned beam imager or laser scanner is operable to scan an object moving through its field-of-view. The system may include means for detecting direction and/or speed of the object. The velocity detection means may include sensors, an interface for receiving velocity information from other system elements, or image analysis that examines the skew, stretch, or compression in images. Responsive to object movement direction and speed, the scanned beam imager may alter its pixel capture rate and/or its scan rate to compensate. Alternatively or in combination, the imager may perform software-based image motion compensation. In some embodiments, the system may allow the image capture region to pace objects moving rapidly through its field-of-view.

A scanning endoscope, amenable to both rigid and flexible forms, scans a beam of light across a field-of-view, collects light scattered from the scanned beam, detects the scattered light, and produces an image. The endoscope may comprise one or more bodies housing a controller, light sources, and detectors; and a separable tip housing the scanning mechanism. The light sources may include laser emitters that combine their outputs into a polychromatic beam. Light may be emitted in ultraviolet or infrared wavelengths to produce a hyperspectral image. The detectors may be housed distally or at a proximal location with gathered light being transmitted thereto via optical fibers. A plurality of scanning elements may be combined to produce a stereoscopic image or other imaging modalities. The endoscope may include a lubricant delivery system to ease passage through body cavities and reduce trauma to the patient. The imaging components are especially compact, being comprised in some embodiments of a MEMS scanner and optical fibers, lending themselves to interstitial placement between other tip features such as working channels, irrigation ports, etc.

Aspects of the subject matter described herein relate to attributing light emissions to spots a light was scanned over. In aspects, the scanned light includes light capable of increasing light emissions from at least one type of matter. A detector detects emitted light that comes from spots the light was previously scanned over. Circuitry attributes emitted light with spots within the area. Data representing light that reflects from each spot may be combined with data representing light that emits (if any) from each spot to create an image. The emitted light may be assigned a false color in the image to distinguish it from reflected light in the image. Emitted light may occur as a result of fluorescent activity. Other aspects are described in the specification.
摘要:
A method includes obtaining a measurement of a property of a light source, scanning light from the light source onto a surface, such that the light interacts with the surface, detecting light from the surface to create a picture element, and correcting the picture element with the measurement of the property. An apparatus includes a scanned beam display, the scanned beam display is configured to receive a signal and to scan the signal for viewing by a user. The signal is to contain picture element information. The picture element information includes information for a plurality of colors, wherein information for at least one color is corrected to substantially remove a perturbation to the picture element information, such that an image containing the picture element information will be substantially unchanged by the perturbation.
