  • DEVICE AND METHOD FOR DETERMINING A VIABILITY AND/OR A CELL COUNT OF BIOLOGICAL CELLS IN A SUSPENSION BY MEANS OF COLLIMATED TRANSMISSION
    Publication number: 20230183635
    Abstract: Devices and methods are provided for determining viability and/or a cell counts of biological cells in a cell suspension culture using collimated transmission. Devices can include an illumination source for generating an electromagnetic illumination beam; beam manipulation means for collimating the illumination beam; and a detection unit for detecting an electromagnetic transmission beam being a portion of the collimated illumination beam which has been transmitted through a sample of the cell suspension culture.

  • Method For Detecting Demineralization Of Tooth Substance
    Publication number: 20220361806
    Abstract: A method for detecting demineralization of a tooth substance, including the steps of irradiating (S101) a structured light pattern onto the tooth substance; detecting (S102) a light intensity of the light pattern remitted from the volume of the tooth substance; and determining (S103) demineralization of the tooth substance based on the detected light intensity.
