Gyroscopes are sensors that measure angular rate and angular orientation. A three-dimensional fused silica micro shell rate-integrating gyroscope is presented. One aspect of the gyroscope includes the use of optical sensors to detect motion of the resonator. The proposed gyroscope is attractive because it achieves several magnitudes higher accuracy as well as high vibration and shock insensitivity from a novel resonator design as well as other unique manufacturing processes.

According to various embodiments described herein, an article comprises a glass or glass-ceramic substrate having a first major surface and a second major surface opposite the first major surface, and a via extending through the substrate from the first major surface to the second major surface over an axial length in an axial direction. The article further comprises a helium hermetic adhesion layer disposed on the interior surface; and a metal connector disposed within the via, wherein the metal connector is adhered to the helium hermetic adhesion layer.

A conductive layer includes a microwave transformer for scaling the intensity of a microwave signal of a first frequency by a scaling factor. The transformer includes a first physical area delimited with a closed curve on the conductive layer for receiving the microwave signal from a first space angle and re-emitting a ray of the microwave signal to a second space angle. A ratio of the first physical area to the second physical area is smaller than 0.5. The ratio of the first effective area to the first physical area is larger than the ratio of the second effective area to the second physical area. The scaling factor is the ratio of the maximal intensity of the re-emitted ray and the intensity of a ray through an open aperture having a physical area equivalent to the second physical area in the same direction than the re-emitted ray.
