Abstract: Imaging techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes receiving a test sample and capturing a plurality of infrared images of the test sample. Each infrared image corresponds to a different range of infrared radiation wavelengths. The method also includes determining a spectral profile of the test sample using the infrared images, comparing the determined spectral profile to a known spectral profile of a material of interest, and determining whether the material is present in the test sample based on the comparing. Additional methods and related devices are also provided.

Abstract: Techniques are disclosed for systems and methods to provide reliable analyte spatial detection systems. An analyte spatial detection system includes an imaging module, a visible light projector, associated processing and control electronics, and, optionally, orientation and/or position sensors integrated with the imaging module and/or the visible light projector. The imaging module includes sensor elements configured to detect electromagnetic radiation in one or more selected spectrums, such as infrared, visible light, and/or other spectrums. The visible light projector includes one or more types of projectors configured project visible light within a spatial volume monitored by the imaging module. The system may be partially or completely portable and/or fixed in place. The visible light projector is used to indicate presence of a detected analyte on a surface near or adjoining the spatial position of the detected analyte.

Abstract: In one embodiment, a method for displaying a panoramic view image includes transmitting video data from a plurality of sensors to a data processor and using the processor to stitch the video data from respective ones of the sensors into a single panoramic image. A focus view of the image is defined and the panoramic image is scrolled such that the focus view is centered in the display. A high resolution camera is aimed along a line corresponding to a center of the focus view of the image and an image produced by the camera is stitched into the panoramic image. A mapping function is applied to the image data to compress the data and thereby reduce at least the horizontal resolution of the image in regions adjacent to the side edges thereof.
