Study on the performance of three-dimensional ghost image affected by target

摘要

The performance of the three-dimensional ghost imaging (3D GI) affected by the targets is theoretically analyzed, and the corresponding models are deduced. Typical targets, including a plane, a sphere and a cone, are employed to analyze the effects on signal-to-noise ratio (SNR) of 3D GI. Results indicate that the performance of 3D GI is affected by the rate of change of the surface height, the tilt angle and the surface roughness of the target to different extent simultaneously. Moreover, increasing the energy of the pulsed laser (PL) and reducing the pulse width of the PL properly are discussed to improve the performance of 3D GI effectively for different characteristics of the targets. Additionally, the different effects from the target characteristics can be used for potential target identification and classification. (C) 2019 Elsevier B.V. All rights reserved.
