Laser diodes allow one to build a very thin, wide-gamut edge-lit backlight system for a direct-
view liquid crystal display. An optical fiber is used to transfer its optical power into a light …

Laser speckle noise occurs owing to the strong interference that originates in the high
coherency of laser light and the surface topography of the screen. The suppression of the …

Two alternative methods for effectively reducing the speckle noise in laser based rear and
front projection displays are studied and demonstrated. Firstly, widening of the laser …

This paper investigates a method to remove hot spot speckle, which is produced by laser-
long coherence, on a projection screen. The objective of the work has been to first create an …

In this paper, the relationship between the coherence and the speckle contrast in a laser-
based projection display system is studied with the consideration of human visual percept …

Speckle is the main obstacle for the use of laser light sources in projection technology. This
paper focuses on speckle suppression by the reduction of temporal coherence which is …

Laser speckle noise occurs owing to the strong interference that originates in the high
coherency of laser light and the surface topography of screen. The suppression of the …

We propose a system that reduces laser display speckles by vibrating the light pipe. A small
displacement of the light pipe appears to allow the total reflection of the laser, thereby …

To evaluate the influence of exposure time on speckle noise for laser displays, speckle
contrast measurement method was developed observable at a human eye response time …

A dynamic light scattering liquid crystal (DLS-LC) device is applied to reduce speckle from a
laser pico-projector. The DLS-LC device produces time-varying scattering patterns, which …
