What is Holographic Laser Projection

See How Holographic Laser Projection Works?

Holographic Laser Projection – or HLP™ – is a revolution in display technology. The term holographic refers to the inventive method we use to create 2D images.

Using holographic algorithms, we transform the image we want to project into sets of diffraction patterns, which are shown on a tiny microdisplay. When laser light illuminates the microdisplay, the projected image is formed by diffraction.

Diffraction patterns are highly efficient. Instead of blocking light, they steer light to exactly where it is needed and away from where it is not. Calculating the diffraction pattern for each high quality image would be too computationally intensive.

By calculating multiple patterns, each of which forms a rough version of the image. When viewed in rapid succession, the eye evens out the noise and perceives a single, clearly defined image. So you get efficient, high quality video in real time.

Using lasers means colours appear rich and vivid, and the image is always in focus. HLP™ technology also projects perfectly onto curved surfaces. Its uniquely wide throw angle creates large images very close to the projector. And HLP™ has a class 1 laser safety classification, making it completely eye safe.

These features enable to integrate infrared sensing technology and create an interactive projector that instantly transforms any flat surface into a touch screen.
