Title: Che-Chih Tsao: Innovator in Volumetric 3D Display Technology
Introduction
Che-Chih Tsao is a prominent inventor based in Arlington, MA (US), known for his groundbreaking work in volumetric 3D display technology. With a total of 12 patents to his name, Tsao has made significant contributions to the field of imaging and display systems.
Latest Patents
One of his latest inventions is the "Active Screen Volumetric 3D Display." This innovative system utilizes a moving display panel that sweeps across a designated display space, allowing for a full volume to be used as the display area. The 3D images are processed into slices based on an orthogonal 3D grid structure, which are then converted into image frames for display. The method involves creating 'image shots' from each frame, which are displayed in sequence to approximate the original image.
Another notable patent is focused on "Methods and Systems of Rapid Focusing and Zooming for Volumetric 3D Displays and Cameras." This invention addresses the need for rapid variable focusing and zooming in the projection of volumetric 3D images. It employs techniques such as inserting thin wedge prisms into the optical path and adjusting their positions to change the optical path length effectively. This allows for precise control over focusing and magnification, enhancing the overall imaging experience.
