  • Patent number: 9809842
    Abstract: Systems, devices, and methods for accurately imaging chemiluminescence and other luminescence are disclosed. A compact, flat-bed scanner having a light-tight enclosure, one or more detector bars of linear charge-coupled device (CCD) or complementary metal oxide semiconductor (CMOS) imaging chips, and high working numerical aperture (NA) optics scans closely over a sample in one direction and then the opposite direction. Averages or other combinations of intensity readings for each pixel location (x, y) between the two or more passes are averaged together in order to compensate for luminescence that varies over time. On-chip pixel binning and multiple clock frequencies can be used to maximize the signal to noise ratio in a CCD-based scanner.

  • Patent number: 9366630
    Abstract: Quantitative fluorescence imaging systems and methods using angular illumination to obtain automatic focus information. Laser scanning (e.g., point or line scanning) with angular illumination in combination with an area imaging sensor, such as with a bi-telcentric scanner, is used to determine sample height (relative to a detection axis orthogonal to a platform holding the sample) and also correct for sample height in subsequent scans.
