Abstract: A superconducting nanowire photon detection array adjusts a number of the array elements, a lens array that 1) splits transmitted lights into multiple beams that equals the number of the array elements, and are converged in to a superconducting nanowire detection area; 2) a pulsed laser detects a surface of an object, transmits reflected different light pulses by the surface of the object through the lens array, and records a round-trip time of each photon; 3) collects the photons detected by each array element, takes the array elements as pixels and calculates a gray value of the pixels; and 4) plots a gray-scale image by taking the pixels as pixel points, calculates a distance between the object and the pixel points, and reconstructs a three-dimensional image of the object.

Abstract: A superconducting nanowire photon detection array adjusts a number of the array elements, a lens array as an photon alignment system, splits transmitted lights into a plurality of beams, and converges the plurality of beams to a superconducting nanowire detection area; detects a surface of an object by adopting a pulsed laser, transmits different light pulses reflected by the surface of the object through the lens array, and records a round-trip time of each photon; collects the photons detected by each array element, takes the array elements as picture elements, and calculates a gray value of the picture element; and plots a gray-scale image by taking the picture elements as pixel points, calculates a distance between the object and the pixel points, and reconstructs a three-dimensional image of the object and the distance between the object and the pixel points.
