Patent ID: 8384625

Claim:
A scanning beam display system, comprising: a fluorescent screen comprising a plurality of elongated fluorescent stripes, each elongated fluorescent stripe operable to emit visible fluorescent light in response to receiving excitation light; an optical module operable to produce an excitation light beam and scan the excitation light beam across a series of positions on the screen in a scanning direction, wherein the excitation light beam comprise a series of optical pulses, each optical pulse targeting a respective one of the series of positions on the screen, and wherein the optical module is operable to shape a beam cross-section of each optical pulse such that the cross-section is elongated along a respective fluorescent stripe, the respective fluorescent stripe being located at a screen position that is targeted by the optical pulse; and a signal modulation controller, the signal modulation controller configured to adjust a timing of each optical pulse such that the optical pulse targeting the screen position at which the respective fluorescent stripe is located is turned on when a footprint of the optical pulse overlaps with a center portion of the respective fluorescent stripe in the scanning direction and turned off when the footprint of the optical pulse is offset from the center portion of the respective fluorescent stripe in the scanning direction.
