A printing device () includes a laser source and a LCOS-SLM (Liquid Crystal on Silicon Spatial Light Modulator). The printing device generates a laser control signal and a LCOS-SLM control signal. The laser source () generates a plurality of incident laser beams based on the laser control signal. The LCOS-SLM () receives the plurality of incident laser beams, modulates the plurality of incident laser beams based on the LCOS-SLM control signal to generate a plurality of holographic wavefronts () from the modulated plurality of incident laser beams. Each holographic wavefront forms at least one corresponding focal point. The printing device cures a surface layer or sub-surface layer () of a target material () at interference points of focal points of the plurality of holographic wavefronts. The cured surface layer of the target material forms a three-dimensional printed content.

Dynamic holography focused depth printing device

A display device accesses holographic data corresponding to an image. A laser source generates a laser light. A SLM (Spatial Light Modulator) receives the laser light and modulate the laser light based on the holographic data of the image. A partially transparent reflective lens receives the modulated laser light and reflects the modulated laser light towards an eye of a user of the display device. A holographic image is formed in the form of a reconstructed wavefront based on the modulated laser light. The partially transparent reflective lens is disposed adjacent to the eye of the user.

Near eye dynamic holography

A printing device () includes a dynamic holography printing application configured to generate a laser control signal and a LCOS-SLM (Liquid Crystal on Silicon Spatial Light Modulator) control signal based on a two-dimensional content corresponding to a lithography mask. A laser source () generates a plurality of incident laser beams based on the laser control signal. A LCOS-SLM () modulates the plurality of incident laser beams based on the LCOS-SLM control signal, generates a plurality of holographic wavefronts (), each holographic wavefront forming at least one corresponding focal point. The LCOS-SLM generates a plurality of distinct focused light field regions () at interference points of focal points of the plurality of holographic wavefronts. The plurality of distinct focused light field regions correspond to the two-dimensional content.
