    摘要: A stereo projection optical system includes a polarizing beam splitter, a 2-way wheel, a digital micro-mirror device, and a total internal reflection prism. The polarizing beam splitter is configured for emitting two light outputs. The 2-way wheel includes a reflective region and a transmissive region. The reflective region is configured for reflecting the light outputs and the transmissive region is configured for transmitting the light outputs. The digital micro-mirror device is configured for superimposing spatial information on the light outputs. The total internal reflection prism configured for coupling the light outputs of the 2-way wheel into the digital micro-mirror device and transmitting a light output of the digital micro-mirror device. The stereo projection optical systems provide viewers three-dimensional images formed by two alternative polarized light beams whose polarizations are perpendicular to each other utilizing the 2-way wheel.

    摘要: A testing method is configured for testing parameters of a color wheel. The color wheel includes a color filter, which includes three sector-shaped filter segments and a motor for driving the filter segments of the color filter to rotate. The color filter is driven to rotate. Light is emitted toward the color filter of the color wheel, and reflected back by the color filter. Boundary impulses are generated according to changes in intensity of the light reflected back by the color filter. Based on relationships between the boundary impulses, central angles of the filter segments of the color wheel are calculated.

    摘要: A testing system measures central angles of filter segments of a color wheel. The color wheel includes a color filter, which includes three sector-shaped filter segments and a motor for driving the filter segments to rotate. The testing system includes a sensor and a processor. The sensor emits light toward the color filter and receives light reflected back by the color filter, and generates an impulse signal according to intensity changes of the light reflected back by the color filter. The impulse signal includes a plurality of boundary impulses corresponding to boundaries formed between adjacent filter segments. The processor calculates central angles of the filter segments according to relationships between the boundary impulses.

    摘要: A system for detecting blemishes on a surface of an object includes at least an image capturing apparatus, at least a light source assembly, and a data processing device. The image capturing apparatus is configured for an image of a surface of an object and acquiring a brightness value of each of pixels of the image. The light source assembly is configured for light the surface. The data processing device is electrically connected to the image capturing apparatus and configured for calculating sum of all of the brightness value to obtain a mean value of the brightness values, comparing the brightness value of each pixel with the mean value and marking the pixels as a blemish whose brightness value is greater than the mean value. The system and method avoid errors that may otherwise occur due to the interference of noise, and avoid the subjective factors of viewers.
