Abstract: Methods and apparatus for providing dynamically adjusted radiated signals are disclosed. In one aspect, a method of detecting one or more objects in a path of travel of a vehicle may include generating a laser with radiated power. The method may further include emitting the laser in a direction of travel of the vehicle and receiving one or more reflections of the emitted laser reflected from the one or more objects located in the direction of travel of the vehicle. The method may also further include generating a signal indicating that the one or more objects are in a path of the vehicle based on the received one or more reflections. The method may also include dynamically adjusting the radiated power of the laser based on an input corresponding to one or more of (i) a current speed of the vehicle or (ii) a current position of the vehicle.

Abstract: An example LIDAR system includes a detector, an amplifier, a time-to-digital converter (TDC), an integrator, an analog-to-digital converter (ADC), and a processor. The detector is configured to receive a reflected light pulse, where the reflected light pulse is reflected off of an object. The amplifier is coupled to the detector to generate an analog signal in response to the reflected light pulse. The TDC is coupled to the amplifier to generate a first time data and a second time data in response to the analog signal. The integrator is coupled to the amplifier to integrate the analog signal. The ADC is coupled to the integrator to sample an output of the integrator and to generate a digital sample. The processor is configured to process the first time data, the second time data, and the digital sample to estimate a total reflected energy of the reflected light pulse.
