Lidar interference filters
Web4 Thin-Film Interference Filters for LIDAR Ultra-narrow bandpass filters are the most common type of interference filter used to isolate LIDAR return signals (Figure 3). These filters can be designed with bandwidths as narrow as 0.1 nm without sacrificing transmission, which is typically greater than 90%. The basic design relies on Fabry-Pérot Web30. jun 2024. · Optical interference filters are needed to separate the LiDAR light from the solar background. In the absence of optical filtering, the detector would be swamped with the solar background, rendering the LiDAR invisible. LiDAR is a time- of- flight technique capable of measuring the distance to objects in front of the sensor.
