Holographic mesh projector screens work by projecting two images simultaneously. One image is projected onto the screen, while another image is projected onto a thin mesh screen positioned in front of the main screen. The mesh screen is made up of tiny holes that allow light to pass through. When the two images are superimposed, they create a 3D image that appears to float in mid-air.
The holographic effect is achieved by the way the mesh screen diffracts the light. The tiny holes in the mesh screen cause the light to diffract in different directions, creating the illusion of depth. The result is a stunning 3D image that appears to be suspended in mid-air.
Holographic mesh projector screens require a powerful projector with high brightness and contrast. The projector needs to be able to project two separate images simultaneously with minimal crosstalk. The mesh screen also needs to be positioned at a precise distance from the main screen to achieve the desired effect.
