Patent number: 11567002Abstract: A system for the identification of micro-organisms includes an irradiation unit adapted to sequentially provide coherent electromagnetic radiation of one or more wavelengths along a common optical path. A holder is adapted to retain a substrate having a surface adapted for growth of a micro-organism colony. A beamsplitter is adapted to direct the coherent electromagnetic radiation from the common optical path towards the retained substrate. An imager is arranged opposite the beamsplitter from the retained substrate and is adapted to obtain images of backward-scattered light patterns from the micro-organism colony irradiated by the respective wavelengths of the directed coherent electromagnetic radiation. Some examples provide radiation of multiple wavelengths and include an imager arranged optically downstream of the retained substrate to obtain images of forward-scattered light patterns from the micro-organism colony irradiated by the wavelengths of radiation.Type: GrantFiled: September 2, 2020Date of Patent: January 31, 2023Assignee: Purdue Research FoundationInventors: Euiwon Bae, Arun K. Bhunia, Edwin Daniel Hirleman, Huisung Kim, Bartlomiej Rajwa, Joseph Paul Robinson, Valery Patsekin

Publication number: 20200401787Abstract: A computer method for correlating depictions of colonies of microorganisms includes receiving an image of a substrate associated with a first time and showing a colony of microorganisms. A second image of the same substrate and associated with a second time shows a candidate colony of microorganisms. A region of the second image that shows the candidate colony of microorganisms is located. The first region of the first image is compared to the second region of the second image. Based on the comparison of the images, the candidate colony of microorganism is determined to be the same colony as the first colony of microorganisms. Systems for moving substrates having colonies of microorganisms and maintaining orientation of the substrates before and after movement are also described.Type: ApplicationFiled: September 8, 2020Publication date: December 24, 2020Applicant: Purdue Research FoundationInventors: Joseph Paul Robinson, Bartlomiej Rajwa, Valery Patsekin

Patent number: 7280204Abstract: A multi-spectral detection and analysis system detects and classifies a targeted sample. The system may include a light source that causes the targeted sample to luminesce. A light dispersion element disperses the luminescence to a photodetector in a photodetector array. Each photodetector in the array transmits a signal indicating a portion of the spectrum to a multi-channel collection system. The multi-channel collection system processes the signal into a digital signal and forms the digital signal into a spectral signature. A processor analyzes the spectral signature and compares the spectral signature to known spectral signatures to identify the targeted sample.Type: GrantFiled: April 8, 2005Date of Patent: October 9, 2007Assignee: Purdue Research FoundationInventors: Joseph Paul Robinson, Bartlomiej Rajwa, Gérald Grégori, Valery Patsekin
