  • Publication number: 20230175838
    Abstract: A measurement apparatus for measuring a laser focus spot size, which includes a two-dimensional image detector and an imaging system which forms a magnified image of a focus spot located an object plane onto the image detector. The imaging system includes at least an objective lens. A sealed liquid container is secured over a part of the objective lens such as the optical surface of the objective lens is immersed in the liquid (e.g. water) within the container. The liquid container has a window through which the laser beam enters. An image processing method is also disclosed which processes the image obtained by the image detector to obtain the focus spot size while implementing an algorithm that corrects for the effect of ambient vibration.

  • Publication number: 20230165717
    Abstract: An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed tangential to a parallel of latitude of the surface of the lenticule and then then moved in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, with the orientation of the scan line rotated between successive sweeps. To generate tissue bridge free incisions without leaving laser-induced marks in the eye, a laser pulse energy between 40 nJ to 70 nJ is used, and the sweeping speed is controlled such that the scan line step (the distance between the centers of consecutive scan lines) is between 1.7 ?m and 2.3 ?m.

  • Patent number: 11654052
    Abstract: An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed by the XY and Z scanners at a location tangential to a parallel of latitude of the surface of the lenticule. The XY and Z scanners then move the scan line in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, and a prism is used to change the orientation of the scan line of the high frequency scanner between successive sweeps. In each sweep, the sweeping speed along the meridian is variable, being the slowest at the edge of the lenticule and the fastest near the apex.

  • Publication number: 20230150665
    Abstract: An automatic spraying unmanned aerial vehicle (UAV) system based on dynamic adjustment of early warning range and a method thereof are disclosed. In the automatic spraying UAV system, an unmanned aerial vehicle analyzes a forward direction and a forward speed of a staff appearing in an environment video, calculates a preset distance, and generates an early-warning range by extending outwardly a spraying range by a preset distance; when determining the staff appears within the early-warning range in the environment video, the unmanned aerial vehicle pauses an automatic spraying operation, so as to achieve the technical effect of improving safety of the staff in an operation area by dynamically adjusting the early-warning range of the automatic spraying operation of the unmanned aerial vehicle.

    Abstract: An ophthalmic surgical laser system includes: a laser that produces a pulsed laser beam having a pulse energy and pulse repetition rate; a high frequency fast scanner; an XY-scan device; a Z-scan device; and a controller. The controller controls the high frequency scanner to produce a scan line having a scan width; controls the XY-scan device and the Z-scan device to carry out of first sweep of the scan line in a first sweep direction and to carry out a second sweep of the scan line in a second sweep direction that is not parallel to the first sweep direction thereby defining an overlap region. At least one of the pulse energy, repetition rate, XY-scan speed, and the scan width is varied so as to accelerate the cutting speed and reduce the exposure of ophthalmic tissue in the overlap region to multiple exposures of laser pulses configured to modify ophthalmic tissue.

  • Publication number: 20220378615
    Abstract: A method implemented in an ophthalmic surgical laser system for forming a corneal flap in a patient's eye with improved bubble management. The flap includes a horizontal bed and a vertical or near vertical side cut around the periphery of the bed except for an uncut hinge area. The side cut has a bubble barrier layer that can prevent bubbles formed by the laser-tissue interaction from escaping into an interface between the corneal and the patient interface lens. In some embodiments, the bubble barrier layer is a thin uncut layer, located in the epithelium of the cornea, that separates the side cut into two portions. In other embodiments, the side cut does not reach the anterior corneal surface, leaving an uncut bubble barrier layer located with the epithelium. In other embodiments, an additional side cut portion is formed through the uncut bubble barrier layer as the last step.

  • Publication number: 20220257415
    Abstract: Systems and methods for adjusting an angle of incidence of a laser surgery system include a laser source to produce a laser beam and an optical delivery system to output the laser beam pulses to an object at an adjustable incident angle. A first rotator assembly receives the beam from the laser source along a first beam axis. The first rotator assembly rotates around the first beam axis and the first rotator assembly outputs the beam along a second beam axis different from the first beam axis. A second rotator assembly receives the beam from the first rotator assembly along the second beam axis. The second rotator assembly rotates around the second beam axis. The second rotator assembly follows the rotation of the first rotator assembly and the first rotator assembly is independent of the rotation of the second rotator assembly.
