Coherent Two-Photon LIDAR Shatters Range Limitations

Researchers have made a breakthrough in LIDAR technology with the development of coherent two-photon LIDAR, which overcomes the range limitations imposed by coherence time. By utilizing two-photon interference of thermal light beyond coherence, this new technique allows for accurate and precise ranging of remote objects situated far beyond the coherence time dictated by the spectral bandwidth of the light source. The Coherent Two-Photon LIDAR is robust to turbulence and ambient noise, making it highly applicable in challenging environments. This advancement has the potential to revolutionize industries reliant on precise distance measurements, such as autonomous vehicles, robotics, and environmental monitoring.
