Abstract
Provided are a lidar system and an autonomous driving system using the same. The lidar system includes: a light emitter configured to include a light source generating a laser beam and a scanner moving the laser beam from the light source to scan an object with the laser beam; a receiving sensor configured to convert light reflected and received by the object into an electrical signal; and a signal processor configured to include a trans impedance amplifier amplifying an output signal of the receiving sensor, an analog to digital converter converting an output signal of the trans impedance amplifier into a digital signal, and a gain controller varying a gain of the trans impedance amplifier. According to the lidar system, an autonomous vehicle, an AI device, and an external device may be linked with an artificial intelligence module, a drone, a robot, an Augmented or Virtual Reality device, etc.
