    Abstract: A scanning projector and method is provided that that uses at least one multi-stripe laser to generate the laser light for the scanned image. Specifically, the multi-stripe laser includes at least a first laser element and a second laser element formed together on a semiconductor die. The first laser element is configured to output a first laser light beam, and the second laser element is configured to output a second laser light beam. At least one scanning mirror is configured to reflect the first laser light beam and the second laser light beam, and a drive circuit is configured to provide an excitation signal to excite motion of the at least one scanning mirror. Specifically, the motion is excited such that the at least one scanning mirror reflects the first laser light beam and the second laser light beam in a raster pattern of scan lines.

    Abstract: A system for variable distribution of light is provided. The system comprises: a plurality of reflective optical devices having a first variable reflective beam splitter configured to receive light along an input light path and direct a first portion of the light along a first light path and direct a second portion of the light to another one of the plurality of reflective optical devices, and a last reflective optical device configured to receive remaining light from a second last reflective optical device and to perform one of: direct the remaining light along a last light path; and, divide the remaining light into two portions, and direct the two portions along two different light paths. At least one optical property of one or more of the plurality reflective optical devices is adjustable to variably apportion received light. Moreover, said system for variable distribution of light can further comprise a plurality of projectors configured to receive one or more of: the first portion, the remaining light and at least one of the two portions.

    Abstract: An image drawing apparatus (100) includes a light source unit (110) that outputs a laser light, a sensor (115) that measures an index regarding brightness of the laser light, a scanner (120) that reflects and scans the laser light, and an image processor (111) that controls the light source unit (110), outputs the laser light to a drawing area narrower than a scanning area of the scanner (120) so that an image based on image data that has been input is drawn, outputting an adjustment laser light to adjust the brightness of the laser light to an outside of the drawing area, stops the output of the adjustment laser light when a period until the time the output of the adjustment laser light becomes stable is passed after the output of the adjustment laser light is started, and adjusts the brightness of the laser light based on the index regarding the brightness of the adjustment laser light. The period until the time the output of the adjustment laser light is stopped can be varied.

    Abstract: An optical device and an image projection apparatus including the same are disclosed. The optical device includes a laser diode for outputting a laser light having a predetermined wavelength, a polarization separator for transmitting a first polarized light of the laser light and reflecting a second polarized light of the laser light, a wheel including a wavelength conversion unit for converting a wavelength of the second polarized light of the laser light reflected by the polarization separator such that the second polarized light of the laser light corresponds to one selected from among a blue light, a green light, and a red light and a transmission unit for transmitting the other lights, a polarization converter for converting the light transmitted through the wheel into the first polarized light and outputting the converted first polarized light to the wheel, and an optical output unit for outputting the first polarized light from the polarization converter and the light converted in wavelength and reflected by the wheel. Consequently, it is possible to provide a compact optical device that is capable of achieving highly efficient light output.

    Abstract: An illumination devices using excitation light and a wavelength conversion material to generated converted light for illumination, where the wavelength conversion material is excited by multiple excitation lights from both sides to achieve increased brightness. The excitation lights incident on the two sides of the wavelength conversion material may have the same color or different colors. Light separation structures are provided on both sides of the wavelength conversion material to separate the excitation light and the converted light. Light separation may be based on color difference or etendue difference of the excitation light and converted light. In one particular example, wavelength conversion material is formed on a surface of an LED which acts as the first excitation light source, and a second excitation light is delivered through a light separation structure onto the other side of the wavelength conversion material.
