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

Patent number: 11200822Abstract: A non-transitory computer-readable medium encoded with a computer-readable program, which when executed by a processor, will cause the processor to execute an image processing method, the image processing method including establishing a zero crossing region from a target image onto a screen, wherein the zero crossing region comprises a corresponding value. The method further includes receiving a variable input and an integration time input, wherein the variable input comprises a frequency number for an image accumulation procedure, and wherein the integration time comprises a time period for which an aperture for a sensor receives incoming signals. Additionally, the method includes performing the image accumulation procedure. Moreover, the method includes producing a final greyscale image by adding a plurality of sets of vertically shifted pixel values, wherein the frequency number for the image accumulation procedure ranges from 3 to 20.Type: GrantFiled: July 14, 2020Date of Patent: December 14, 2021Assignee: Purdue Research FoundationInventors: Euiwon Bae, Huisung Kim
