Material identification through image capture of raman scattering |
| abstract |
A hand-held sized imaging instrument identifies molecules with high selectivity and in complex mixtures. The instrument uses inelastic scattering and scattering intensities from with machine learning algorithms based on convolutional neural networks (CNN's) to identify the presence of a specified chemical or combination of chemicals. A laser is housed within the instrument to initiate a material response of a sample using laser light of a specified wavelength. The instrument uses an image sensor to capture visible images with inelastic scattering information. The CNN is able to classify the image to determine whether the specified chemical or combination of chemicals is present in the sample. The instrument is inexpensive, portable, easy to use by anyone (nonchemist, nonprofessional), and safe (laser is completely housed). The instrument can be used efficiently and easily for quality control, security, and other applications to reliably detect the presence of specified substances. |
