    摘要: An apparatus and method may provide uniform illumination on the retina using scanned continuous wave laser sources by making use of waveguides with regular shaped cross sections. Some embodiments of the present invention may provide illumination uniformity for selected spots and/or whole target scans, and may provide for constant dwell times every point of the scanned beam. Furthermore, the non-uniformities caused by starting and stopping scans may be eliminated by, for example, clipping-off both the beginning and end of the scan with a hard aperture. A modulator may be provided, enabling uniform irradiation of selected target areas.

    摘要: A method for delivering electromagnetic radiation onto tissue to be ‘treated with the radiation includes delivering the radiation onto the tissue in a treatment-spot having a polygonal shape such as a rectangle or a hexagon. The polygonal shape is selected such that a region of the tissue to be treated’ can be completely covered by a plurality of such shapes essentially without overlapping the shapes. The radiation to be delivered is passed through a lightguide having a cross-section of the polygonal shape. Radiation exiting the lightguide is projected onto the tissue via a plurality of optical elements to provide the treatment-spot.

    摘要: A scanning optical system for delivering electromagnetic radiation onto tissue to be treated is cooperative with a lightguide or optical fiber. Radiation to be delivered is provided by a source thereof via the optical fiber. The optical system includes an optical projection arrangement comprising a plurality of lenses cooperatively arranged with the lightguide. A first of the lenses is arranged to receive radiation emerging from the lightguide. The beam of radiation is passed through the projection arrangement to form a treatment spot the radiation on the tissue. Scanning is effected by causing relative motion between the exit-end of said lightguide and at least the first lens, transverse to the optical axis of the projection arrangement. The treatment spot undergoes a related transverse motion over the tissue. In one example scanning is effected by moving the first lens with the lightguide fixed. The first lens is moved using an arrangement of piezo-electric actuators.

    摘要: The present invention is directed to an optical grating sensor configured to detect a phase change in light passing though the system due to a binding event caused by an analyte. The grating sensor may include a light source that may be, for example, a coherent light source. The invention may also include a first diffraction grating having a first period. A micro-electrical mechanical system (MEMS) may be displaced from the first diffraction grating and may be configured to modulate the light received form the coherent light source. An analyte recognition material may be disposed on the surface of the first grating. A detector may be configured to receive light form the coherent light source after the light has been diffracted from the first diffraction grating and modulated by the MEMS. In another embodiment of the present invention, the grating sensor may be configured to operate in two modes. The first mode may be a mode the detect a phase change in the light due to a binding event. The second mode may include the detection of fluorescence due to a binding event and may employ tagging of the analytes.

    摘要: A beam delivery system for treating target tissue that includes an input for receiving a light beam, a variable attenuator for providing variable attenuation of the light beam, a power and wavelength detection assembly, a spot size adjustment assembly, and a controller. The power and wavelength detection assembly measures the power level of the beam, and detects when unwanted wavelengths are present in the light beam. The spot size adjustment assembly selectively feeds the beam through different optical fibers to achieve different spot sizes of the beam. The controller controls the variable attenuator, the power and wavelength detection assembly, and the spot size adjustment assembly to achieve the desired power and wavelength, and beam spot size.
