  • Patent number: 11927873
    Abstract: The object of the invention relates to a method for scanning with an optical beam (50) using a first acousto-optic deflector (15, 15?) having an optical axis along a Z-axis and at least one acousto-optic crystal layer (14), involving directing the optical beam (50) in the first acousto-optic deflector (15, 15?), and deflecting the optical beam (50) along an X-axis perpendicular to the Z-axis by means of the first acousto-optic deflector (15, 15), during which generating a plurality of acoustic chirp signals (30) in the at least one acousto-optic crystal layer (14) of the acousto-optic deflector (15, 15?) by—generating a first acoustic chirp signal (30a) having a duration of ? in the acousto-optic crystal layer (14), then—generating a second acoustic chirp signal (30b) in the acousto-optic crystal layer (14) within a ? period of time counted from the start of the generation of the first acoustic chirp signal (30a).

  • Publication number: 20220011558
    Abstract: The invention relates to a method for correcting motion artifacts of in vivo fluorescence measurements using a 3D laser scanning microscope containing two pairs of orthogonally arranged acousto-optic deflectors, the method comprising: selecting a region of interest, selecting a plurality of guiding points along the region of interest, extending the guiding points to objects selected from scanning lines and/or surface elements and/or volume elements which, together, substantially cover the region of interest, repeatedly scanning the objects by generating continuous drifts to cover the objects, projecting the obtained scanning data to frames and obtaining a time series of the frames, correcting motion artifacts by shifting the data of the successive frames with respect to each other so as to maximize fluorescence cross correlation between the data of the frames.

  • Patent number: 11156819
    Abstract: A method for scanning along a substantially straight line (3D line) lying at an arbitrary direction in a 3D space with a given speed uses a 3D laser scanning microscope having a first pair of acousto-optic deflectors deflecting a laser beam in the x-z plane (x axis deflectors) and a second pair of acousto-optic deflectors deflecting the laser beam in the y-z plane (y axis deflectors) for focusing the laser beam in 3D. Further, a method for scanning a region of interest uses a 3D laser scanning microscope having acousto-optic deflectors for focusing a laser beam within a 3D space defined by an optical axis (Z) of the microscope and X, Y axes that are perpendicular to the optical axis and to each other.
