  • Patent number: 10955649
    Abstract: A method for optical microscopy, including using a first laser beam to excite dye particles in a sample region with light having a first wavelength. A second laser beam with a second wavelength based on the emission spectrum of the excited particles is used to de-excite the excited particles. The first and second beams have first and second respective intensity distributions which are spatially different when co-aligned; the second profile has a minimum where the first has a maximum. The region is once concurrently illuminated with the first and second beams, and an emission signal is detected. For each scanning point, the region is illuminated also with a pulse of the second laser beam or continuously prior to or after illuminating the region of the sample concurrently with both lasers. The illumination with only the second laser beam defines a background signal that is subtracted from the emission signal.

  • Patent number: 10908088
    Abstract: A scanning element routes a sheet or beam of excitation light through a first set of optical components and into a sample at an oblique angle. The position of the excitation light within the sample varies depending on the orientation of the scanning element. Fluorophores within the sample emit fluorescent detection light. The first set of optical components route the detection light back to the scanning element, and the scanning element routes the detection light through a second set of optical components and into a camera. The second set of optical components includes a phase modulating element that induces a controlled aberration so as to homogenize point spread functions of points at, above, and below a focal plane when measured at the camera. In some embodiments, the images captured by the camera are processed to correct for aberration by performing deconvolution of a point spread function.
