Claim 0:
1. A light detection and ranging (LiDAR) apparatus comprising:
a continuous wave light source configured to generate continuous wave light;
a frequency modulator configured to drive the continuous wave light source such that the continuous wave light source generates frequency-modulated continuous wave (FMCW) light;
a beam steering device configured to emit the FMCW light to an object for a first period of time and stop emitting the FMCW light to the object for a second period of time;
a receiver configured to receive the FMCW light that is reflected from the object to form a reception signal; and
a signal processor configured to obtain distance information and speed information about the object based on the reception signal,
wherein the frequency modulator is configured to linearly increase or decrease a frequency of the FMCW light for a third period of time including the first period of time and the second period of time, and
wherein the third period of time is equal to or greater than a sum of the first period of time and the second period of time.
