摘要:
An analyzer apparatus and method of use thereof is described to dynamically irradiate a sample with incident light where the incident light is varied in time in terms of any of: position, radial position relative to a point of the skin of a subject, solid angle, incident angle, depth of focus, energy, and/or intensity. For example, the incident light is varied in radial position as a function of time relative to one or more of a sample site, a point on skin of the subject, a detection optic, and/or a sample volume observed by a detection system. The radially varied incident light is used to enhance and/or vary light probing the epidermis, the dermis, and/or the subcutaneous fat of the subject or of a group of subjects.

Techniques and systems are disclosed for electronic target recognition. In particular, techniques and systems are disclosed for performing electronic surveillance and target recognition using a multiple parallax exploitation (MPEX) electronic eye platform. Among other things, a MPEX system can include an imaging unit that includes multiple image capture devices spaced from one another to form an array to provide overlapping fields-of-view and to capture multiple overlapping stereo images of a scene. The MPEX system can also include a processing unit connected to the imaging unit to receive and process data representing the captured multiple overlapping stereo images from the imaging unit to characterize one or more objects of interest in the scene.

A biosensing device for detecting biological analytes, and methods of use and manufacture, are disclosed. The device includes a biosensing element that can remain implanted for extended periods of time. The biosensing element is connected to an optical fiber terminating outside of the body. The optical fiber is also connected to an information analyzer. The information analyzer receives light from the reaction of fluorescent molecules in the biosensing element. The biosensing device can be used to detect and analyze the effectiveness of chemotherapy agents and molecules associated with various diseases.

An implantable intraocular pressure sensor device for detecting excessive intraocular pressure above a predetermined threshold pressure is disclosed. The device includes a pressure switch that is sized and configured to be placed in an eye, wherein said pressure switch is activated when the intraocular pressure is higher than the predetermined threshold pressure. The device is optically powered and transmits data wirelessly using optical energy. In one embodiment, the pressure sensor device is a micro electromechanical system.
摘要:
A micro electromechanical system (MEMS) broad band incandescent light source includes three layers: a top transmission window layer; a middle filament mount layer; and a bottom reflector layer. A tungsten filament with a spiral geometry is positioned over a hole in the middle layer. A portion of the broad band light from the heated filament is reflective off the bottom layer. Light from the filament and the reflected light of the filament are transmitted through the transmission window. The light source may operate at temperatures of 2500 K or above. The light source may be incorporated into an on board calibrator (OBC) for a spectrometer.
摘要:
A process for forming GaAs on a silicon substrate with very low levels of unintended silicon doping. First, a dielectric layer of silicon dioxide, silicon nitride, or both is grown or deposited on the substrate. Next, a window is opened in the dielectric layer exposing the silicon substrate in the regions in which the GaAs is to be formed. The GaAs layer is then formed on the substrate using conventional techniques with the gas phase transfer of silicon contamination from the edges and back of the silicon substrate to the GaAs region inhibited by the dielectric layer or layers.
