Title: David J Vickrey: Innovator in Crystal Growth Technology
Introduction
David J Vickrey is an accomplished inventor based in Vancouver, WA (US). He has made significant contributions to the field of crystal growth technology. His innovative approach has led to the development of a unique method for measuring the diameter and melt of crystals during their growth process.
Latest Patents
David holds a patent for a method that utilizes a CCD camera to measure the diameter of a growing crystal. This method employs optical recognition of the luminous ring at the crystal-melt interface. The invention aims to eliminate the negative effects of orbit, melt-level, and incorrect camera angle. The CCD camera is strategically positioned to focus on half of the crystal's circumference as it grows. An automatic control system measures the diameter using two diametrically opposed points on the crystal and computes the melt level error with a third point closest to the camera. This system optimizes crystal diameter by controlling the crucible height and crystal pull rate.
