Abstract: A receiver for a light detection and range finding system is disclosed. The receiver can include an optoelectrical device to receive a pulse of light reflected from a target and to convert the pulse of light to a current pulse. The receiver can also include a transimpedance amplifier (TIA) to convert the current pulse to a voltage pulse. The receiver can also include a tunable filter that has an input coupled to an output of the TIA. The tunable filter can have a frequency response that is adjustable. The TIA and the tunable filter can be disposed on a single integrated circuit (IC) die.

Abstract: An electronic circuit assembly comprises a circuit substrate including a top surface, a bottom surface, and a cavity formed at an edge of the circuit substrate that exposes an intermediate surface between the top surface and the bottom surface of the circuit substrate; and a laser diode including a top surface, a bottom surface, and a side surface; wherein the bottom surface of the laser diode is arranged on the intermediate surface of the circuit substrate.

Abstract: A system and method can be provided for introducing a varying time delay between a sequence of electrical pulses in a laser range finding system. A laser beam can be modulated with the sequence of electrical pulses. The laser beam can be transmitted towards a target and a photosensitive element can receive the modulated laser beam after reflection by the target. Control circuitry can determine a distance between the laser range finding system and the target based on the varying time delay, such as to provide a reduced error in the distance determination.
