A laser projector may contain one laser light source for single-color projection or three sources for RGB (red, green, and blue) full color projection. Lasers offer potentially brighter projected images as compared to a conventional projector, with more vibrant colors.
The 1.06 mm diameter distal tip houses the lens system, which determines the imaging parameters. Prototype systems provide a 70-degree field-of-view and 10-micron resolution. Laser sources are coupled into the single scanning fiber and they use red, green, and blue lasers to create color images.
The first commercially available laser-based DLP HDTV was the Mitsubishi L65-A90 LaserVue in 2008, which also eliminated the use of a color wheel. Three separate color lasers illuminate the digital micromirror device (DMD) in these projection TVs, producing a richer, more vibrant color palette than other methods.
A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Combining a pico projector with a webcam, a laser pointer, and image processing software enables full control of any computing system via the laser pointer. Pointer on/off actions, motion patterns (e.g., dwell, repetitive visit, circles, etc.) and more can all be mapped to events which generate standard mouse or keyboard events, or user ...
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display.
A projector in a standard form factor: The PG-D2870 projector from Sharp, which uses Digital Light Processing technology An image from a video projector in a home cinema. A video projector is an image projector that receives a video signal and projects the corresponding image onto a projection screen using a lens system.
Laser Doppler imaging (LDI) is an imaging method that uses a laser beam to image live tissue. When the laser light reaches the tissue, the moving blood cells generate Doppler components in the reflected (backscattered) light. The light that comes back is detected using a photodiode that converts it into an electrical signal.
