  • Patent number: 9039224
    Abstract: A head-mounted pointing device is disclosed, and can be used for example for surgical training. The pointing device includes a frame or harness assembly made from a circumferential headband and a cross strap that extends over the user's (i.e. trainer's) head. A laser pointer is mounted on one side of the circumferential headband, and a battery pack is provided to power the laser pointer. An user-operated pneumatically controlled switch is used to toggle the laser pointer. By moving the user's head and by activating the switch to engage the laser pointer, the trainer can point to a given target, such as material to be surgically excised from the patient during a surgical procedure.

  • Publication number: 20150138774
    Abstract: Provided is a laser optic module including: a laser light source which generates laser light; a beam guide which includes a light path whose side wall is a reflective surface to introduce the laser light into the light path to guide the laser light; and a fluorescent substance which is provided at a point where the light path of the beam guide ends and emits fluorescence by the laser light, in which a width of the light path is formed by a full width at half maximum (FWHM) of the laser light in a position where the laser light is incident onto the fluorescent substance. Therefore, the laser light is directly used to improve luminance efficiency and reduce a size by adopting a simple structure.

  • Publication number: 20150133732
    Abstract: An otoscopic instrument includes an instrument housing having a distal end and an opposing proximal end, each end defining a viewing axis of the instrument. A laser light source is disposed in relation to the viewing axis. At least one optical element is configured to direct emitted light from the laser light source toward a target of interest through the distal end of the instrument housing and in which reflected laser light is directed toward the proximal end along the viewing axis. The laser light source can be contained within a releasably attachable laser module to selectively permit separate white light and laser viewing modes of the instrument.

  • Patent number: 9028106
    Abstract: A headlamp disclosed includes: a laser diode for emitting a laser beam; a light emitting section including a fluorescent material which emits light in response to excitation light emitted from the laser diode; a light-transmitting heat conducting member which is provided so as to face a laser beam irradiation surface of the light emitting section and receive heat of the light emitting section; and an adhesive layer filling a gap between the heat conducting member and the laser beam irradiation surface. This arrangement improves efficiency of the heat conducting member in absorbing the heat of the light emitting section, and consequently cools the light emitting section efficiently.

  • Publication number: 20150117011
    Abstract: A laser emitting device includes a laser plane source for providing planar surrounding light, a reflector, and a connection mechanism. The reflector surrounds the laser plane source and has a reflective sidewall facing the laser plane source. The reflective sidewall includes a plurality of reflective surfaces connected to each other. Each of the reflective surfaces has an individual angle relative to the planar surround light. The planar surrounding light hits one of the reflective surfaces and forms a laser ring emitted from the laser emitting device. The connection mechanism allows the reflector to be moved relative to laser plane source. A size of the laser ring can be changed by changing the reflective surface to be hit.

  • Patent number: 9010965
    Abstract: A system is provided having a multiplexed laser source which combines the outputs of multiple lasers into multiplexed illumination which is then externally modulated to provide output illumination having reduced or zero speckle. Each of the laser sources are turned ON and OFF (gated) in a timed sequence to provide multiplexed illumination having a time-averaged speckle contrast that is lesser than the speckle contrast of the output of any one of the lasers. The output of one or more lasers may also be wavelength multiplexed, where the lasers operate at different wavelengths, and/or polarization multiplexed. An external modulator receives and modulates the multiplexed output in phase and/or modal power distribution to further reduce the speckle in the output of the system. The multiplexed laser source and external modulator can be used as separate apparatuses for reducing speckle in laser illumination.

  • Patent number: 8998474
    Abstract: A surface light source device includes a surface light-emitting light-guiding unit; an LED light source disposed at an outside position on a side of a direction of the light incident surface; a plurality of laser light sources disposed at an outside position on a side of a direction of a rear surface of the surface light-emitting light-guiding unit; and a laser-light-ray guiding unit arranged on a side of a rear surface of the surface light-emitting light-guiding unit. The laser-light-ray guiding unit guides the laser light rays emitted from the laser light sources so that the laser light rays enter through a light incident end surface, travel in a direction opposite to a direction in which the LED light source emits the LED light ray, and thereafter are reflected by a light bending part to enter through the light incident surface of the surface light-emitting light-guiding unit.
