Abstract

A laser display system is disclosed for displaying real time data by modulating a light beam from a laser, converting the beam of light to a curved path of light and transforming the path light into successive straight lines. The straight lines of video information are then projected into a spaced relation to one another to form a display.

Claims

1. In a projection system including substantially diffractionlimited optical means for transforming a modulated laser light beam operating in the uniphase mode into successive horizontal traces, said optical means having an aperture sized to pass substantially only the uniphase mode of said light beam and comprising the combination of a mirror driven so as to project said modulated light beam into a series of circular traces, a fiber optic device for receiving said circular traces of modulated light and transforming them into a series of horizontal line segments of modulated light, and an oscillating vertical scan mirror for receiving said horizontal line segments and projecting them in spaced relationship with each other to form a display. 2. A display system comprising in combination laser means operable in the uniphase mode for emitting a visible light beam, a substantially diffraction-limited optical system having an aperture sized to pass substantially only the uniphase mode of said light beam which includes means for modulating said light beam, a horizontal scanner to convert said modulated light beam into a circular pattern, a fiber optic device to transform said circular pattern into a linear horizontal trace, and a vertical scanner to project successive horizontal traces in a spaced relationship to each other to form a display.

3. A display system comprising in combination laser means operable in the uniphase mode for emitting a visible light beam, means for modulating said light beam, a substantially diffraction-limited optical system having an aperture sized to pass substantially only the uniphase mode of said light beam which includes a horizontal scanner to convert said modulated light beam into a circular pattern, a fiber optic device to transform said circular pattern into a linear horizontal trace, and a vertical scanner to project successive horizontal traces in a spaced relationship to each other to form a display.

4. A display system comprising in combination laser means operable in the uniphase mode for producing a visible light output having at least two colors, a substantially diffraction-limited optical system having an aperture sized to pass substantially only the uniphase mode of said light output which includes means for modulating said light output, a horizontal scanner to convert said modulated light output into a circular pattern, a fiber optic device to transform said circular pattern into a linear horizontal trace, and a vertical scanner to project said successive horizontal traces in a spaced relationship to each other to form a color display.

5. A display system comprising in combination laser means operable in the uniphase mode for producing a visible light output having at least two colors, means for modulating said light output in accordance with video signals, a substantially diffraction-limited optical system having an aperture sized to pass substantially only the uniphase mode of said light output which includes a horizontal scanner to convert said modulated light output into a circular pattern, a fiber optic device to transform said circular pattern into a linear horizontal trace, and a vertical scanner to project said successive horizontal traces in a spaced relationship to each other to form a color display.
