Patent number: 9983005Abstract: Methods and apparatus optically measure acceleration, without Sagnac-effect corruption, without requiring slow light and without moving parts. Each optical accelerometer includes at least one measurement cell and at least one reference cell. Two optical signals traverse the cells in opposite directions around a figure-8-configured optical path and then interfere to produce an output signal. The reference cells have different indices of refraction than the measurement cells. Acceleration differentially affects speeds of the optical signals traversing the measurement and reference cells through differentially affecting the indices of refraction of the measurement and reference cells. These differences are evident in changes in the interference in the output signal, thereby enabling measurement of the acceleration. Several embodiments, including optical bench, vertical slab multi-pass, toroidal prism, planar waveguide, cylindrical waveguide, wound waveguide and optical fiber, are described.Type: GrantFiled: February 3, 2017Date of Patent: May 29, 2018Inventor: Marvin A.

Patent number: 9976909Abstract: An apparatus and method for controlling stray radiation within a CVD chamber. A heater array disposed beneath a wafer carrier for radiatively heating of the wafer carrier includes a peripheral or outermost heating element or elements. Scattered radiation originating from a designated segment of the peripheral heating element(s) can be reduced locally by one of several mechanisms, including reducing the emission (e.g., operating temperature) of the designated segment, or capturing or deflecting a portion of the radiation originating from the designated segment. In one embodiment, an electrical connector on a resistance heating element provides the reduced emission from the designated segment. It has been found that radiation thermometers fixed proximate an axis that extends from the center of the wafer carrier and across the designated segment is subject to less stray radiation, thus providing a more reliable temperature reading in the optical wavelengths.Type: GrantFiled: May 29, 2015Date of Patent: May 22, 2018Assignee: Veeco Instruments Inc.Inventors: Gurary Tas, Jing Zhou, Daewon Kwon
