摘要:
A first location comprising an unknown material may be scanned using SWIR hyperspectral imaging in a dual polarization configuration. Surveying may also be applied to thereby determine whether or not a human is present. This surveying may be achieved my assessing LWIR data, data acquired from motion sensors, and combinations thereof. If no human is present, a second location may be interrogated using Raman spectroscopic techniques to thereby obtain a Raman data set representative of the region of interest. This Raman data set may be assessed to associate an unknown material with a known material. This assessment may be achieved by comparing the Raman data set to one or more reference data sets in a reference database, where each reference data set is associated with a known material.
摘要:
A method for detecting unknown materials, such as drugs. A first location is surveyed using a video capture device to identify a second location comprising an unknown material. The second location is interrogated using SWIR spectroscopic and/or imaging methods to generate a SWIR hyperspectral image. The SWIR hyperspectral image is analyzed to associate the unknown material with a known drug material. A system for detecting unknown materials, such as drugs comprising a first collection lens for collecting interacted photons from a first location and a visible imaging device for generating a visible image. A second collection lens may collect a plurality of interacted photons from a second location and a tunable filter may filter the interacted photons. A spectroscopic imaging device may detect the interacted photons and generate a SWIR hyperspectral image. A processor may analyze the SWIR hypespectral image to associate an unknown material with a known material.

摘要:
An endoscope has an improved chip-on-tip configuration that includes both a first configuration of source illumination fibers and a second plurality of source illumination fibers, along with a camera chip. The combination of the camera chip and the source illumination fibers on the tip of the endoscope results in endoscopes with reduced size and weight.

摘要:
The present disclosure provides systems and methods for determining the presence of a target material in a sample. In general terms, the system and method disclosed herein provide collecting interacted photons from a sample having a target material. The interacted photons are passed through a tunable filter to a VIS-NIR detector where the VIS-NIR detector generates a VIS-NIR hyperspectral image representative of the filtered interacted photons. The hyperspectral image of the filtered interacted photons is analyzed by comparing the hyperspectral image of the filtered interacted photons to known hyperspectral images to identify the presence of a target material in a sample. The systems and methods disclosed herein provide easy identification of the presence of a target material in a sample.
