Title: Sidney Weiser: Innovator in Crystallography and Optical Equipment
Introduction
Sidney Weiser is a notable inventor based in Silver Spring, MD (US). She has made significant contributions to the fields of crystallography and optical equipment measurement. With a total of 2 patents, her work showcases innovative methods and apparatuses that enhance the understanding and quality of optical systems.
Latest Patents
One of her latest patents is titled "Method of and apparatus for real-time crystallographic axis orientation." This invention involves scanning a specific small area of a crystal sample with a laser beam that rotates about an axis perpendicular to the sample surface. The intersection of the beam with a plane above the surface describes a true spiral or stepwise spiral pattern. The varying reflectance from different beam positions produces a pattern indicative of crystallographic orientation.
Another significant patent is "Apparatus for measuring the quality of optical equipment." This invention determines the quality of optical equipment by measuring its modulation transfer function. The apparatus includes a uniformly curved, elongated opaque sheet member with a data pattern of discrete spatial frequency. A rotatable mirror reflects an incident image onto the stationary reticle, allowing for the assessment of the optical equipment's quality through the modulation of transmitted light.
