  • Patent number: 9591734
    Abstract: In laser-produced plasma (LPP) extreme ultraviolet (EUV) systems, pressure waves and other impulsive disturbances originating from plasma bubble emitting EUV light are created which affect flight of incoming droplets. These disturbances slow the migration of subsequent droplets to the plasma bubble. Because the incoming droplets are slowed, the laser beam does not directly hit the droplet at a primary focus point. This causes the resulting level of EUV light generated to be lower than expected and is manifested as a periodic oscillation in the LPP EUV system. An iterative learning controller (ILC) is used to reduce the periodic oscillations when operating the LPP EUV system in a burst mode or a continuous mode. The ILC, on the rising edge of each burst, uses an error signal collected during a completed burst and the input control signal from the completed burst to update the input control signal for a next burst.

  • Patent number: 8646110
    Abstract: The present disclosure provides a procedure to obtain the absorption profiles of molecular resonance with ANSOM. The method includes setting a reference field phase to ?=0.5 ? relative to the near-field field, and reference amplitude A?5|?eff|. The requirement on phase precision is found to be <0.3 ?. This method enables ANSOM performing vibrational spectroscopy at nanoscale spatial resolution.

  • Publication number: 20140014858
    Abstract: An infrared laser source system that combines laser emitters through an optical waveguide. Each emitter is coupled to a port of the optical waveguide and the waveguided signal is combined to provide a spatially combined laser source with a single common exit aperture. The materials used for waveguiding allow the propagation of wavelengths in the infrared. The system can be used for combining multiple laser emitters to increase the total output power and/or for combination of multiple emitters with different wavelength for increased spectral coverage out of the laser system.

  • Patent number: 8564879
    Abstract: A composite infrared target simulation display system for field testing of infrared (IR) search and track, guidance and general sensory systems. The system includes one or more tileable emitter arrays scalable without systemic size limitation. The emitter arrays are square faced tiles housing power and control electronics to autonomously display a stored infrared test image according to parameters distributed by a control host and a timing signal. A face of the emitter array is divided into regularly spaced pixel positions, each made up of multiple IR emitters operating in differing regions of the IR band to display an image. Multiple emitter array tiles are joined to form a complete system. Each emitter of each pixel position is individually addressable to be individually controllable with respect to emittance state for displaying an image. Multiple images may be sequentially displayed to replicate a simulated target signature in motion.

  • Patent number: 8491135
    Abstract: An apparatus determines a cursor position in an illumination field of a projector. An obstruction is detected in the illumination field. The cursor position is determined as the point on the obstruction furthest from where the obstruction crosses a border of the illumination field. A distance to the point on the obstruction is determined and compared to a distance to a point not on the obstruction. Gestures are recognized as a function of movement of the obstruction and the determined distances.

  • Publication number: 20130113927
    Abstract: A light projector comprises a stack of layered planar optical elements where the stack comprises a group (103) of planar optical elements (107-111) arranged to provide a plurality of light patterns. The stack may specifically comprise a group of transparent layers having opaque patterns such that light propagating through the layers results in the light patterns. The light patterns reach a microlens array (101) which is arranged to focus the light patterns at different focal distances. In some scenarios, programmable optical elements may be used to generate the light patterns. A vision system may determine characteristics of objects based on reflections of the projected light patterns. The approach may in particular provide an efficient yet low cost light projection system for distance determination.
