Claim 3:
4. The three-dimensional imaging method based on the superconducting nanowire photon detection array according to claim 2, wherein the superconducting nanowire circuit is located at a center of the pixel, and is connected with coplanar superconducting delay lines by connecting the SNSPD and a thin film resistor in parallel; each row of the superconducting delay lines are connected with each other, the thin film resistor has a resistance value between 10Ω and 10000Ω, and the resistance generated by superconducting nanowire photon responses is in an order from kΩ to MΩ; the thin film resistor short-circuits the resistance generated by the SNSPD, and releases a temporary resistance generated by internal superconducting disturbance, and the SNSPD is quickly restored to a superconducting state.
