Patent number: 9077915Abstract: Systems and methods for interweaving infrared and visible moving image data using a single optical system and imager device based on an infrared input signal and a visible input signal are disclosed. Infrared image frames can be substituted in for complete visible image input frames or for partial visible image input frames, i.e. substituting in an infrared image input frame for one or more of the color channels in one or more visible image input frames. Moving video or computer-generated moving graphics can include both infrared and visible image data to be displayed users viewing the resulting images with and without night vision imaging devices. In particular, the system and method can be used in projection systems for night-vision imaging device team training simulators to reduce the cost of the system while increasing the ease of use and performance of such systems.Type: GrantFiled: April 7, 2010Date of Patent: July 7, 2015Assignee: Projectiondesign ASInventors: Kristian Kolstad, Kjell Einar Olsen

Patent number: 8998447Abstract: Embodiments of the present invention provide apparatuses and systems for providing illumination for projectors. Two or more sets of reflectors are used to combine light beams emitted by two or more two-dimensional arrays of light sources to provide a combined light beam with high brightness toward a pupil of a projection system. Solid state light sources, such as diode lasers and LEDs, may be used as light sources at relatively low cost and low powers, and with long lifetime.Type: GrantFiled: September 26, 2012Date of Patent: April 7, 2015Assignee: Projectdesign ASInventors: Oyvind Svensen, Kjell Einar Olsen, Sverre Lefsaker, Tobby Simonsen, Ronny Bjomsen

Patent number: 8905578Abstract: Embodiments of the present invention provide apparatuses and systems for providing illumination for projectors. One or more beam combiners are used to combine multiple light beams to provide a combined light beam toward to a pupil of an imaging device in a projector. Solid state light sources, such as diode lasers and light-emitting diodes (LEDs), may be used as light sources at relatively low cost and low power, and with long lifetime. In one embodiment, an optical beam combiner comprises a first reflective surface, a second reflective surface, and a transparent region disposed between the first reflector surface and the second reflective surface. In another embodiment, an optical device comprising an array of optical beam combiners is provided. In a further embodiment, light sources comprising a plurality of light-emitting devices mounted on curved surfaces are utilized in conjunction with an optical beam combiner to provide illumination for a projector.Type: GrantFiled: September 21, 2012Date of Patent: December 9, 2014Assignee: Projectdesign AGInventors: Oyvind Svensen, Kjell Einar Olsen, Sverre Lefsaker, Tobby Simonsen, Ronny Bjornsen

Patent number: 8702239Abstract: Projection systems and apparatuses for providing high contrast projected images with an aspect ratio different from the aspect ratio of the imager or micro-display used are provided. Light integrators having an aspect ratio equal to the aspect ratio to the desired projected image or video can be inserted into the optical train of the projection system or apparatus to illuminate only an active area equal to having an aspect ratio equal to the aspect ratio of the desired projected image or be. By reducing the illuminated area of the imager, light scattered or otherwise diverted from pixels held in the “off state” in the non-active area of imager can be greatly reduced to provide darker dark levels in the frame surrounding the project image or video.Type: GrantFiled: February 14, 2011Date of Patent: April 22, 2014Assignee: Projectdesign ASInventors: Kjell Einar Olsen, Tobby Simonsen, Sverre Lefsaker, Jørn Eriksen

Patent number: 8622551Abstract: Image projectors with increased light intensity and methods for providing brighter images are provided. Image projectors, described herein, can provide the brightness while still providing any or all of compactness, low power consumption, and long lifetime. To increase brightness, sectional mirrors are used to respectively compress the light from two light sources into a single pupil (e.g. an aperture) of an imaging device. The compression can be accomplished by regions (e.g. sections) of the mirror having different angles with respect to the pupil. Relatively little light may be lost in the compression since minima for a light intensity pattern from a light source may occur between the regions that reflect the light.Type: GrantFiled: July 20, 2012Date of Patent: January 7, 2014Assignee: Projectiondesign asInventors: Odd Ragnar Andersen, Kjell Einar Olsen, Sverre Lefsaker

Publication number: 20130010266Abstract: Systems methods and apparatus for projection system including a control/illumination module and a separate projector head are disclosed. The control/illumination module can be disposed in the location separate from location in which the projector head is disposed and/or used. The projector head can be coupled to the control/illumination module via a control signal connection, and illumination transmission connection and an optional coolant connection. By separating the control/illumination module from the projector head module, many, if not all, noise and heat producing elements can be implemented in the control/illumination module, thus providing a smaller sized, quieter, efficient and lower maintenance projector head that can be installed in implementations in which extraneous noise, heat, and leaked light can be detrimental to the viewing experience.Type: ApplicationFiled: July 5, 2011Publication date: January 10, 2013Applicant: projectiondesign asInventors: Kjell Einar Olsen, Per-Kristian Thogersen, Hans Erik Davidsen, Sverre Lefsaker, Jorn Eriksen

Publication number: 20100208342Abstract: Methods and systems are provided for creating passive 3D images. A color modulator having at least six filters is used to send light to a single imager in respective RGB spectrums during successive time periods for a left-eye image and then in a different RGB spectrum for a right-eye image, or vice versa. Resulting 3D imaging systems can use a single projector and a single imaging chip without the need for specialized display surfaces, and thus are inexpensive to build and have a low maintenance cost. In addition, better color properties between the left and right images may be provided with a color spectrum of a first image having at least two peaks that surround a peak of the corresponding color for the second image. A color shift of the images may thus be decreased without a loss in other color properties.Type: ApplicationFiled: February 19, 2009Publication date: August 19, 2010Applicant: projectiondesign asInventor: Kjell Einar Olsen
