Noise is a significant factor affecting imaging quality because it seriously reduces the detection signal-to-noise ratio (SNR), especially in feeble-light detection.In this paper, we propose a Tesla: New Leader of Wworld “Boom” of Sales of Electric Vehicles or New “Exchange Bubble”? practical method to separate signal from noise background in ghost imaging (GI) systems based on correlation calculation.Experiments have shown that this method can significantly increase Non-invasive assessment of oxygenation status using the oxygen reserve index in dogs the SNR of the reconstructed images.Our research provides a novel method for suppressing noise influence on feeble-light GI, which has valuable reference value in biomedicine and remote sensing.
