Abstract
A LiDAR system comprising one or more tunable filters is provided. The one or more tunable filters can be tuned to compensate for wavelength shifts of light signals caused by ambient environmental changes. The LiDAR system includes a light source providing light signals, a signal steering system configured to direct the light signals to a field-of-view, and temperature monitoring circuitry configured to monitor a temperature shift of the light source. The temperature shift corresponds to a wavelength shift of the light signals from a first wavelength value to a second wavelength value. The system further comprises a tunable filter positioned in a receiving system configured to receive return light signals, and a motor configured to rotate the tunable filter by an angle based on the temperature shift such that a passband of the tunable filter matches the second wavelength value.
