Abstract:
Enhancing infrared measurement accuracy and thereby allowing remote diagnostics of various states that are characterized by minute temperature difference, beyond the capabilities of current infrared imaging systems is provided herein. Embodiments of the invention utilize the exact fusing of a visible light image and an infrared image, achieved by setting the system at a known spatial relationship in which they are both focused at the intersection of their optical axes, and identifying a well contrasting infrared region within a focused visible light image, to visually identify an uninfluenced target region that serves as a reference region for infrared temperature difference measurements. Using this reference allows enhancing the resolution of the infrared imaging by an order of magnitude.
Abstract:
A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes a range imaging camera module that captures the VL and an infrared camera module that captures the IR image. In such examples, the VL image may include a plurality of different portions that each correspond to a different portion of the scene and distance-to-target data associated with each of the different portions of the scene. The camera may align each of the plurality of different portions of the VL image based on the distance-to-target data associated with corresponding portions of the scene so as to correct a parallax error between the VL image and the IR image. The camera may then concurrently display the VL image in alignment with the IR image.

A medical instrument (10, 10') includes at least one medically functional component (20, 22, 24, 100, 102, 104), and an ear coupler (16, 16') adapted for at least partial insertion into an ear canal (EC) to operatively contact the at least one medically iunctional component with a patient. A medically non-iunctional audio player (40) is disposed on the medical instrument, and includes a sound-generating element (42, 42', 44) arranged to generate sound that is audible to the patient when the ear coupler is at least partially inserted into the patient's ear canal, a memory (50) storing relaxing or entertaining audio content, and audio player electronics (48) configured to drive the sound-generating element to play the relaxing or entertaining audio content.
Abstract:
An object (12) concealed in a body (16) is detected by transiently heating or cooling at least part of the body surface, imaging that part of the surface in the mid- or far infrared, and seeking the concealed object (12) in the image(s). Alternatively, the body (16) is imaged as the temperature of its environment fluctuates naturally. Preferably, multiple infrared images are acquired and are processed to provide a measure of the body's thermal diffusivity, the object (12) then being sought according to that measure of thermal diffusivity. Most preferably, the heated/cooled part of the surface is imaged in the visible or near-infrared band too, and the two sets of images are processed together to provide the measure of the body's thermal diffusivity.
Abstract:
A microbridge detector is with an active area that is smaller than a pixel collection area of the microbridge detector. The microbridge detector includes a semiconductor substrate on a first level and a microbridge level disposed above the semiconductor substrate. The microbridge level includes the active area having the pixel collection area greater than a square area of the active area of the microbridge detector. In addition, downwardly extending leg portions are a continuation of the microbridge level and support the microbridge level above the semiconductor substrate so that a thermal isolation gap exists between the microbridge level and the semiconductor substrate. Further, electrically conductive paths are included within the downwardly extending leg portions and connect the active area in the microbridge level to the semiconductor substrate. With this apparatus, the microbridge detector is provided with a pixel collecting area that is larger than a fill factor of the microbridge detector and thus is provided with an enhanced optical collection sensitivity. In addition, with this apparatus, the microbridge detector device can be fabricated with a smaller active area without having to build a smaller microbridge level and thus is not limited by processing techniques.
