摘要： A projection system that includes a singe light modulation device and a plurality of light sources of different wavelengths. Each wavelength of light is incident on the light modulation device at a spatially distinct location and a temporally distinct time. The use of a scanning mirror allows the projection system to sequentially form, in full-color, each of the columns or rows of an image. The projection system is characterized by the reduction of color separation or the rainbow effect due to the rendering of each column or row in full color.

摘要： An invisible scanning safety system for use with laser projection systems that includes sensors monitoring less than the entire laser accessible region such that the region monitored is reduced to almost the absolute minimum, to thereby prevent unwarranted stoppages or disturbances in projection. The system may also monitor a 360 degree region around the lens of the laser projector, a wedge-shaped region, a pyramid-shaped region or a chimney-shaped region.

摘要： A wide angle display system includes a linear array projector, a curved display surface, and an n-sides scanning mirror. The projector is configured to project an image along an optical axis to the scanning mirror. The scanning mirror continuously rotates about a rotational axis at a speed 1/n the refresh rate, so as to reflect and scan the image onto the display surface.

摘要： The invention provides a system and method for reducing laser speckle and interference patterns in a laser projector display when using a laser projector having a spatial light modulator (SLM) with a defined pixel rate. The method can include the operation of polarizing a laser output of a continuous wave laser such that the laser output is s-polarized with respect to a beam combiner. The s-polarized laser output can be divided into a first laser beam and a second laser beam. A phase of the second laser beam can be modulated with an amplitude sufficient to create a phase delay of approximately half a wavelength of the laser output and at a frequency at least twice that of the SLM's pixel rate.

摘要： A system and method is disclosed for reducing visibility of image artifacts caused by diffractive elements in a laser projector having a structured diffractive device. At least two diffracted orders of light can be selected from light emitted from the structured diffractive device using a spatial light filter. The polarization of at least one of the selected diffracted orders can be changed with respect to another selected diffracted order. The selected diffracted order can be recombined to form an image having reduced visible image artifacts.

摘要： A display system able to reduce interpixel intensity gaps caused by the use of pulsed laser sources having relatively short optimum pulse duration. The interpixel intensity gaps are reduced by temporally offsetting multiple laser pulses for a display pixel during a corresponding pixel-scan period. The temporally offset pulses for the display pixel are then scanned to different locations on a viewing surface such that the display pixel has an improved intensity distribution. Additional reduction in the interpixel gaps may be accomplished by de-focusing the temporally offset pulses in a scan direction, increasing the duty cycle of the source lasers, and shifting the location of alternating frames on the viewing surface.
摘要翻译：一种显示系统，其能够减少使用具有相对短的最佳脉冲持续时间的脉冲激光源引起的间隙强度间隙。通过在对应的像素扫描周期期间暂时偏移显示像素的多个激光脉冲来减少像素间的强度间隙。然后将显示像素的时间偏移脉冲扫描到观察表面上的不同位置，使得显示像素具有改善的强度分布。可以通过在扫描方向上对时间偏移脉冲进行去聚焦，增加源激光器的占空比以及在观察表面上移动交替帧的位置来实现像素间隙的附加减少。
