    Abstract: An apparatus or three dimensional (3D) printer is provided for generating a 3D object. The apparatus includes a print chamber and a liquid print matrix such as a photo-curing resin positioned in the print chamber. The apparatus includes an optical assembly focusing light into the print chamber in the form of a real image whose light initiates curing processes for a volume of the liquid print matrix to form the 3D object. The light focused into the print chamber has a wavelength within a wavelength curing range for the photo-curing resin. The real image may be formed using an optical assembly reflecting or redirecting and focusing light reflected from outer surfaces of an existing 3D object. The real image may also be provided in the form of a volumetric image displayed by a volumetric display device displaying planes of a 3D digital model or image of a 3D object.

    Abstract: A method for performing light-based calibration of optics with caustic surfaces. The method includes mapping a light detecting device to a programmable light source. Then, the method includes operating a calibration light source to direct light onto one or more caustic surfaces of an optical assembly, e.g., an assembly of one or more lenses, facets, lenticules, and lenslets. The method may then involve, with the light detecting device, capturing an image of a projection surface of the optical assembly, which is opposite the one or more caustic surfaces in the optical assembly, as the projection surface is illuminated by the light from the light source. Further, the method includes processing the captured image, along with the mapping of the light detecting device to the programmable light source, to generate a calibration map of the optical assembly including the caustic surfaces.

    Abstract: A system for electrostatically levitating an object with a body adapted for receiving a static charge. The system includes an array of at least three electrostatic generators, with each of the electrostatic generators including an exposed element that becomes statically charged during operation of the array. The system also includes a controller operating to generate control signals to the array to independently operate each of the electrostatic generators to provide the static charge at first, second, and third voltages. When positioned in a flight space above the array, the object is levitated above the array of the electrostatic generators by an electrostatic lifting force(s). Each of the electrostatic generators is a high voltage Van de Graaff generator. The first, second, and third voltages are in the range of 0 to 300,000 volts and are varied over time to direct the levitated object along a flight path by the controller.
