An electronic circuit comprises at least one radiation-emitting element (2), a current regulator (12) with a current-producing terminal (O), and a measurement element (14) generating a signal (V.sub.mes) that is representative of the current flowing therethrough. A switch (6) is controlled by a modulation signal (M) so as to open and close, successively, an electrical path passing through the current-producing terminal (O), the radiation-emitting element (2) and the measurement element (14). A conversion circuit (16) is further interposed between the measurement element (14) and the current regulator (12) so as to transform the representative signal (V.sub.mes) into a smoothed signal (S) that is intended for a regulation terminal (Reg). A time-of-flight sensor comprising such an electronic circuit is also provided.

An example method includes receiving, from one or more sensors associated with an autonomous vehicle, sensor data associated with a target object in an environment of the vehicle during a first environmental condition, where at least one sensor of the sensor(s) is configurable to be associated with one of a plurality of operating field of view volumes.

A depth camera assembly (DCA) for depth sensing of a local area. The DCA includes a transmitter, a receiver, and a controller. The transmitter illuminates a local area with outgoing light in accordance with emission instructions. The transmitter includes a fine steering element and a coarse steering element. The fine steering element deflects one or more optical beams at a first deflection angle to generate one or more first order deflected scanning beams. The coarse steering element deflects the one or more first order deflected scanning beams at a second deflection angle to generate the outgoing light projected into the local area. The receiver captures one or more images of the local area including portions of the outgoing light reflected from the local area. The controller determines depth information for one or more objects in the local area based in part on the captured one or more images.

A combined radar and lighting unit includes a laser radar apparatus, a lighting device, and a controller. The laser radar apparatus is mounted to a vehicle, emits laser light toward an outside of the vehicle, and detects reflected light. The lighting device is mounted to the vehicle and emits visible light toward the outside of the vehicle. The controller controls the lighting device to cause the lighting device to alternately operate in a first emission mode to perform emission of the visible light, and in a second emission mode to stop emission of the visible light or reduce a quantity of the visible light. The controller controls the laser radar apparatus to interrupt the measurement of the distance while the lighting device is operating in the first emission mode, and executes the measurement of the distance while the lighting device is operating in the second emission mode.
