    摘要： An optical system for producing electromagnetic radiation with localized increases in irradiance or radiance at the system output includes a first optical mask containing localized regions for producing controlled modifications of phase delays and/or amplitude attenuations and located within the input plane of said optical system. The system also includes at least a single optical component with positive optical power located after the input plane and at least one additional optical mask located after the optical component at non-conjugate locations with respect to the input plane of the system. The additional optical mask contains localized regions for producing controlled modifications of phase delays. Locally increased radiation distributions are produced at the system output.

    摘要： An illumination system and method of illuminating a surgical site are disclosed. One embodiment of the illumination system comprises: a composite illumination source, comprising a plurality of light sources operable to emit a plurality of collinear light beams; and an illumination lens, operable to receive and focus the plurality of light beams at a focal plane; wherein the plurality of collinear light beams are directed onto an off-axis portion of the illumination lens and wherein the illumination lens is aligned co-axially and confocally with an objective lens of an observation device. The light sources can be solid-state lighting devices, such as light-emitting diodes. The observation device can be a surgical ophthalmic microscope. The illumination lens can have a larger diameter than the objective lens, and the off-axis portion of the illumination lens can comprise a Fresnel type lens. The illumination lens can have a clear central portion of a diameter sufficient to prevent interference with the focusing function of the objective lens, or the illumination lens can comprise a ring with a central opening of a diameter sufficient to prevent interference with the focusing function of the objective lens.

    摘要： A diode laser beam combining apparatus for producing a high combined beam power density in the far field at reduced levels of power consumption and heat dissipation includes an array of semiconductor laser emitters arranged in a collinear manner with respect to each other and having an emitter pitch between about 0.7 mm and 2.5 mm. The apparatus also includes a cylindrical lens for collimating emitter beams generated by the array of laser emitters in a direction perpendicular to a junction plane of the laser emitters. The apparatus further includes a micro-optic array and a long focal length cylindrical lens. The micro-optic array is configured to perform a rotational transformation of the collimated emitter beams. The micro-optic array has a lateral spacing in a direction parallel to the junction plane of the laser emitters that matches the emitter pitch. The long focal length cylindrical lens collimates emitter beams in the direction perpendicular to the junction plane after passing through the micro-optic array.

    摘要： A wavelength monitoring device for monitoring a beam of light is disclosed having a beam splitter, with opposing first and second spaced apart faces, for receiving optical radiation from the beam of light to be monitored. In operation the first face reflects a first portion of the optical radiation to a first photodiode. The second face includes a grating for reflecting a second portion of the optical radiation to the first photodiode. The grating also reflects a third portion of optical radiation to a second photodiode. The light received by the second photodiode corresponds proportionally to optical power of the incident beam of light. The first photodiode is for detecting a wavelength characteristic of the composite beam and is located so as to receive the first portion and the second portion of optical radiation after the first portion and the second portion of optical radiation have optically interfered to form a composite beam. The first face and the grating are oriented and spaced from one another so that the first and second portions of the optical radiation optically interfere with one another along a path toward the first photodiode.

    摘要： A method of performing coherent transformations of optical fields includes forming a far field distribution of the input optical field. A fraction of the formed far field is diffracted by producing localized discontinuities within said far field. A Fraunhofer diffraction pattern of the diffracted optical field is formed. The Fraunhofer diffraction pattern is modified by producing localized optical path differences within the Fraunhofer diffraction pattern. The transformed output optical field is produced in the far field with respect to the modified Fraunhofer diffraction pattern.
