Title: Innovations by David B Stegall: A Pioneer in 3D Imaging Technology

Introduction

David B Stegall, an innovative inventor based in Saint Paul, Minnesota, has made significant contributions to the field of 3D imaging technologies. With a remarkable portfolio of 10 patents, Stegall has developed solutions that enhance the capabilities of intra-oral imaging, enabling practitioners to achieve greater precision and efficiency in dental procedures.

Latest Patents

Among his latest inventions, Stegall has created two noteworthy patents. The first is a **Projected texture pattern for intra-oral 3D imaging**, which presents an apparatus designed for powder-free intra-oral 3D imaging. This innovative tool utilizes a projector to emit a random texture pattern of light onto the teeth to be imaged. A digital image sensor captures the reflected texture pattern, allowing for high-quality imaging without the use of powder. The system employs polarizers within the optical path to ensure clarity by suppressing unwanted scattered light.

The second patent is a **3D image capture apparatus with cover window fiducials for calibration**. This apparatus enhances the depth of field to create electronic images of an object, facilitating the generation of a 3D digital model. It features a housing with strategically positioned mirrors that relay images from an external object to an image sensor. The inclusion of apertures within the optical path allows for the transmission of the image through multiple channels, while a transparent cover embedded with fiducials aids in calibration processes.
