Wide range distance measurement over 50 km based on highly sensitive detection of the two-photon absorption photocurrent from a Si-APD

We studied a wide range distance measurement system based on highly sensitive detection of the two-photon absorption photocurrent from a Si-APD. The measurable distance was investigated theoretically and experimentally in detail. The experimental results agreed well with the theory. We demonstrated...
