Laser-based display technologies offer many advantages over traditional lamp and CRT displays, including wider color gamuts, higher luminance and accurate colors. Laser displays create images by modulating the intensity of a laser beam with video information, deflecting it using galvanometers (scanners), mechanical mirror devices or acousto-optic devices. Compact Microlaser Systems Microlaser systems offer compactness and …
Acousto-optic modulators (AOMs) enable you to rapidly switch on or off laser beams or modulate their intensity by means of light interaction with acoustic waves in an optically polished piece of crystal or glass. An electric signal is used to vibrate a transducer attached to an acousto-optic crystal or glass, creating soundwaves that scatter light …
Optic Data Storage System features an objective lens and disk with reflective material, along with a low-powered laser scanning the surface to detect variations in reflectivity of pits and lands on its surface, thus decoding sequences of digital bits of 0s and 1s. Researchers are actively developing strategies to significantly expand optical storage capacity, including …
Laser Doppler anemometry is a technique for measuring flow velocity using the Doppler effect, using two monochromatic laser beams that converge at an intersection point to form an anemometric measurement volume. Particles carried by flowing fluid scatter the light of both beams, causing their frequencies to fluctuate based on velocity, which can then be detected …
