Abstract

At the visible wavelengths range phase modulating Spatial Light Modulators are used for a growing number of imaging-like applications (e.g. holographic projection, 3D holographic displays or structured illumination). Compared to the use of conventional imaging display technologies like LED backlights or LED front illumination, the use of LCOS based phase SLMs for holographic reconstruction using laser illumination, shows the advantage of providing higher light efficiency and with that the same performance or higher brightness using lower powers. The image is generated by diffraction (redistribution of light) instead of blocking light (amplitude modulation) like at conventional projection systems. We demonstrate a setup for color sequential holographic projection using standard components: LETO-3 or LUNA Spatial Light Modulator, HOLOEYE diffractive projection engine and FISBA Ready Beam RGB laser.
