Abstract
Upconversion detection is a promising technology for measurement of IR signals in the 1.5 µm – 2 µm region used for lidar remote sensing [1-2]. In comparison to conventional InGaAs detector, the upconversion detector can achieve IR detection with better signal-to-noise ratio (SNR), not only due to lower dark noise directly, but also because of its limited field-of-view and acceptance bandwidth that results in a much lower background noise.
