Hybrid lidar system capable of generating and detecting multiple waveforms in real time

A hybrid LiDAR system comprising:

• a light source configured to generate reference light;
• a first transmitting part configured to modulate the reference light to generate a pulse signal;
• a second transmitting part configured to modulate a frequency of the reference light to generate a frequency-modulated signal;
• a single optical detector configured to receive a reflected pulse signal and a reflected frequency-modulated signal generated by the pulse signal and the frequency-modulated signal;
• and
• a main controller connected to the single optical detector and configured to use the reflected signals acquired by the single optical detector to acquire three-dimensional images,
• wherein the single optical detector comprises:
• a first receiving part configured to detect a coherent signal generated by interference of an LO signal of the second transmitting part and the reflected frequency-modulated signal;
• and
• a second receiving part provided adjacent to the first receiving part and configured to detect the reflected pulse signal.
