An actively tunable narrow band optical filter structure is located upstream of the photodetector structure to filter out wavelengths of light associated with sunlight prior to being received by the photodetector structure. The filter structure is constructed and arranged to change optical filtering thereof so as to change wavelengths of light permitted to pass there-through. A photodiode detects light passing through the filter structure. A control unit is associated with the photodiode and the filter structure and is constructed and arranged such that based on the light detected by the photodiode, the control unit can cause the filter structure to change the optical filtering thereof by heating or rotating the filter structure so as to compensate for drifting or broadening of a wavelength of the transmitter unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wavelength adaptive narrow band optical filter for a LIDAR system","description":"A LIDAR system includes a transmitter unit constructed and arranged to generate light and a photodetector structure for detecting received, reflected light.
