Described herein are systems and methods that detect an electromagnetic signal in a constant interference environment. In one embodiment, the electromagnetic signal is a light signal. A constant interference detector may detect false signal 'hits' generated by constant interference, such as bright light saturation, from valid signals. The constant interference detector determines if there is constant interference for a time period that is greater than a time period of the valid signal. In one embodiment, if a received signal exceeds a programmable threshold value for a programmable period of time, when compared to previously stored ambient light, a control signal is generated to inform the next higher network layer of a sudden change in ambient light. This control signal can be used to either discard the present return or process the signal in a different way. A constant interference detector may be a component of a LIDAR system.

Systems and methods for detecting an electromagnetic signal in a constant interference environment

Described herein are systems and methods that create a capacitive link based on a rotating cylinder capacitor. A cylindrical rotor rotates around a shaft and maintains an air gap between the cylindrical rotor and the shaft and to create one or more air gap capacitors. A first subsystem, comprising a light detection and ranging components, is coupled to the rotor. A second sub-subsystem, comprising data analysis functions, is coupled to the shaft. The first subsystem and the second subsystem are coupled via capacitive links created by the air gap capacitors. The communication signaling utilized on the capacitive links may be bi-directional and differential signaling. The first subsystem and the second subsystem may comprise a LIDAR light detection and ranging system. The second subsystem may power the first subsystem via inductive coupling.
