Image laser projector that using a laser source and a digital or analog mask projects an image in particles suspended in the air

A device for displaying images in particles suspended in the air that can be viewed by an observer as three dimensional suspended images along a shaped beam of light, as the result of a laser light beam source passing through an electronically controllable mask or filter that shapes the laser light to create a particular image, which is stored in the device, in the suspended particles in the air (“projected image beam”), comprising:

• One or more sources of light to generate, using an optical subsystem (e.g. lens), a collimated laser beam in the visible spectrum, and
• An electronically digital controllable mask or filter including a plurality of selectively active (“on” or “off”, open or close) elements positioned in the paths between the source of light and the final projected image beam. Each of the selectively activate elements has the properties to block, attenuate, change the distribution, redirect, channel, or filter the spatial frequencies of the light when activated or closed. Each of the selectively activate elements respond to a respective electronic signal to block, attenuate, change the distribution, redirect, channel, or filter the spatial frequencies the passage of the light along the respective path, and
• A controller (logical units) that manages one or more controllable masks to shape the light into a projected image beam with the image stored in the controller. The controller is connected to one or more input signals that singularly and collectively determine the image to be displayed.
• A store component that stores the different mask images, encoded into the different input signals. The controller accesses this storing device to retrieve the instructions, associated with an input signal, to program the electronically controllable.
