A circuit board system includes one or more first circuit boards and a second circuit board disposed independently from the one or more first circuit boards and configured to supply power to the one or more first circuit boards. Each of the one or more first circuit boards is configured to be connected to at least one of one or more input/output assemblies configured to receive/transmit optical signal. The second circuit board includes a first interface figured to be electrically connected to a main control circuit board of a gimbal, an inertial measurement unit electrically connected to the first interface, and one or more second interfaces each being electrically connected to one of the one or more first circuit boards.

Disclosed herein are configurations and methods to produce very low loss waveguide structures, which can be single-layer or multi-layer. These waveguide structures can be used as a sensing component of a small-footprint integrated optical gyroscope. By using pure fused silica substrates as both top and bottom cladding around a SiN waveguide core, the propagation loss can be well below 0.1 db/meter. Low-loss waveguide-based gyro coils may be patterned in the shape of a spiral (circular or rectangular or any other shape), that may be distributed among one or more of vertical planes to increase the length of the optical path while avoiding the increased loss caused by intersecting waveguides in the state-of-the-art designs. Low-loss adiabatic tapers may be used for a coil formed in a single layer where an output waveguide crosses the turns of the spiraling coil.

A method for ascertaining a change in a spatial orientation of a nuclear magnetic resonance (NMR) gyroscope having a diamond doped with color centers includes applying a static external magnetic field in a first direction, polarizing a nuclear spin of the color centers of the diamond in a direction of the static magnetic field, and generating a cophasal Larmor precession of the nuclear spin of the color centers of the diamond through application of an alternating magnetic field in a second direction perpendicular to the first direction, whose frequency corresponds to the Larmor frequency of the nuclear spin of the color centers. The method further includes measuring a phase of the Larmor precession, and ascertaining a change in the spatial orientation in a plane perpendicular to the first direction based on a deviation of the precession frequency from an expected value.

A method of creating a privacy mask from an image imaged by an imaging device in which a rotation axis of a camera and a center of a lens do not match includes measuring a distance from the camera to an object in a first imaging condition; creating a first mask for the object, and storing the distance together with the first mask; and creating a second mask for the object in a second imaging condition and correcting a position of the second mask using. the first mask and the distance, wherein an imaging angle of the camera the first imaging condition is same as the imaging angle of the camera in the second imaging condition, and wherein a position of the lens in the first imaging condition is reversed around the rotation axis from a position of the lens in the second imaging condition
