Patent number: 10895500Abstract: An optical measurement method and system. The system includes, and method applies, a light source, a beamsplitter, at least one filter, a output photodetector for acquiring data of a sample, and a correction photodetector for correcting and maintaining output intensity from the light source. The filter is located between the light source and the correction photodetector for normalizing the spectrum of the input light being applied to input light correction. The filter may be incorporated into the beamsplitter and may be tuned to filter light from the light source for providing non-zero transmission of light with a near-zero gradient for wavelengths in a portion of the spectrum of the input light being applied to the sample and read by the output photodetector. The filter may also or alternatively be located downstream of the beamsplitter to correct for wavelength sensitivity of the correction photodetector.Type: GrantFiled: April 29, 2020Date of Patent: January 19, 2021Assignee: ALBERTA BIOPHOTONICS INC.Inventors: Elmar Prenner, Kirat Singh
