Abstract: Disclosed herein are methods, systems, and devices that relate to light detection and ranging (LIDAR). A controlling means for a LIDAR system includes a means for determining a current operational state of the LIDAR system regarding a predefined threshold state. The controlling means also switches the LIDAR system from a first operational mode to a second operational mode when the determined operational state exceeds the predefined threshold state. The second operational mode corresponds to an operational power of at least one operational means of the LIDAR system being lower than in the first operational mode.

Abstract: Techniques for shielding an optical sensor are described. An example of an electronic device includes an optical sensor and a combined light-focusing and electrical-shielding unit disposed over the optical sensor. The light-focusing and electrical-shielding unit has two portions. The first portion gathers light and focuses the light on the electrical sensor. The second portion encloses sides of the first portion and is coated with an electrically conductive material to shield the optical sensor from electromagnetic interference.
