    摘要： A focusing, collimating, and beamsplitting test system for testing laser rangefinders for their beam quality, ranging accuracy, and sight unit alignment. The system includes holographic optical elements in place of conventional mirrors, lenses and beamsplitters. The advantages of this system are that it not only reduces the size and weight of optical elements, but also reduces the number of required elements. Consequently, the resulting test equipment requires less labor to assemble and is more compact and much lighter than conventional test systems.

    摘要： A laser probe for electrically steering a light beam includes a tubular-shaped housing, an optical waveguide, and a beam steering cell. The optical waveguide is disposed within an interior region of the housing and is configured to emit a light beam travelling in a first direction. The beam steering cell is disposed within the housing and comprises an electro-optical (EO) material. The beam steering cell is configured to receive one or more voltages and electrically steer the light beam with the OE material to a second direction. The EO element has a shape of varying thickness such that a first portion of the light beam passes through a portion of EO element having a greater thickness than a second portion of the EO element passed through by a second portion of the light beam. The laser probe may be a directional laser probe or a multi-spot laser probe.

    摘要： An ophthalmic endoilluminator is provided. The ophthalmic endoilluminator includes a light source, a first optical assembly, an optical coupling element, and an optical fiber having an optical grating located distally on the optical fiber, the optical fiber optically coupled to the optical coupling element. The first optical assembly receives and substantially collimates the white light. The optical coupling element receives the substantially collimated white light from the first optical assembly and directs the light to an optical fiber. The optical grating couples to the distal end of the optical fiber, the optical grating having a surface relief grating, and an overlayer optically coupled to the surface relief grating. The optical grating is operable to substantially diffract incident light into N diffraction orders, the N diffraction orders having a substantially uniform intensity.

    摘要： A variable-angle, wide-angle illuminator is disclosed, one embodiment being a small-gauge, variable-angle illumination surgical system comprising: a light source for providing a light beam; an optical cable, optically coupled to the light source for receiving and transmitting the light beam; a handpiece, operably coupled to the optical cable; an optical fiber, operably coupled to the handpiece, wherein the optical fiber is optically coupled to the optical cable to receive and transmit the light beam; an optical assembly, optically coupled to a distal end of the optical fiber, for receiving the light beam and providing the light beam to illuminate a surgical field; and a cannula, operably coupled to the handpiece and optical assembly, for housing and directing the optical assembly to illuminate a selected area, such as a surgical site. The optical assembly can comprise, for example, a fiber/polymer-dispersed-liquid-crystal (“PDLC”) diffuser optically coupled to an optical needle or a nested compound parabolic concentrator (“CPC”) cone. In the PDLC diffuser/needle embodiment, the fiber can be a standard endo-illuminator optical fiber with 0.50 NA or similar value. The light beam from the light source is emitted from the distal end of the optical fiber and provided to the PDLC diffuser for further transmission. The degree of diffusion of the light beam at the PDLC diffuser can be electrically controlled and can be varied from no diffusion to very high degree of diffusion. After passing through the PDLC diffuser, the light beam is provided to a needle or fiber, such as a glass needle or fiber, that transmits the light beam to the surgical site in the eye.
