Title: The Innovations of Wilfrid B Veldkamp
Introduction
Wilfrid B Veldkamp is a notable inventor based in Lexington, MA (US). He has made significant contributions to the field of optical technology, holding a total of 10 patents. His work focuses on advanced optical apparatuses and methods that enhance the efficiency and functionality of light manipulation.
Latest Patents
Among his latest patents, Veldkamp has developed a diffractive microstructure for color separation and fusing. This optical apparatus is designed to disperse a visible light spectrum into primary color bands, directing each band into specific pixelated cells of a passive display. The apparatus features an array of refractive microlenses that are arranged parallel to the plane of the display, such as a liquid crystal display. Additionally, a diffraction grating is positioned in close proximity to the lens array, allowing the microlenses to focus visible light onto the display while the grating separates the light into primary color bands.
Another significant patent involves high-efficiency, multilevel diffractive optical elements. This method employs high-resolution lithography, mask aligning, and reactive ion etching. It involves generating at least two binary amplitude masks, exposing a photoresist layer on an optical element substrate through the first mask, and then etching. This process is repeated for subsequent masks to create a multistep configuration, resulting in an optical element that is highly efficient.
Career Highlights
Veldkamp has worked with prestigious organizations, including the Massachusetts Institute of Technology and the United States of America as represented by the Secretary of the Air Force. His experience in these institutions has allowed him to contribute to cutting-edge research and development in optical technologies.
