Light Pulse Generator, also referred as Optical Pulse Generator, refers to a device that generates optical pulses (in lieu of electrical pulses). The pulses are typically variable by rep rate, pulse width, amplitude (in this case intensity), delay and width of pulse.
Light pulses, particularly with fast risetimes, are idea for detector and PMT testing, optical characterization, benchtop simulation and optical component R&D (lens, collimator, refraction devices, etc.). Generally the light is coupled to one's test configuration via optical fiber. The light may be coupled via multi-mode, single-mode and even PM (polarization maintaining) fiber. A practical industrial application is the simulation of laser return signals into laser rangefinding detectors and their associated electronics. Here the adjustable width, delay and low jitter of a light pulse generator offers an alternative to a do-it-yourself project.
Light pulse generators provide light in a variety of wavelengths. Typical wavelengths include 450 nm, 904 nm, 1064 nm, 1550 nm and 1570 nm. Light Pulse Generators are classified and regulated by the FDA Center for Devices and Radiological Health - http://www.fda.gov/cdrh/radhealth/contactus.html

Famous quotes containing the words light, pulse and/or generator:
“If we see light at the end of the tunnel,
It’s the light of the oncoming train.”
—Robert Lowell (1917–1977)
“I drink the air before me, and return
Or ere your pulse twice beat.”
—William Shakespeare (1564–1616)
“He admired the terrible recreative power of his memory. It was only with the weakening of this generator whose fecundity diminishes with age that he could hope for his torture to be appeased. But it appeared that the power to make him suffer of one of Odette’s statements seemed exhausted, then one of these statements on which Swann’s spirit had until then not dwelled, an almost new word relayed the others and struck him with new vigor.”
—Marcel Proust (1871–1922)
