- Abstract
- Recent quantum imaging technologies, compared to the classical imaging technologies, have shown advantages on the image resolution, contrast and signal-to-noise ratio[1,2,3]. This research aims to reproduce the beneficial properties of quantum imaging such as breaking the classical resolution limit and high image contrast. It is expected that faster and concise quantum imaging setup while maintaining the distinctive image properties. The covariance processing of correlated photon intensity demonstrates enhanced characteristics compared to the classical average intensity profile. The contrast-to-noise ratio of quantum imaging is improved from 0.8 to 3.0. This difference could be further enhanced by capturing additional frames. Additionally, the spatial resolution of the resolution target showed a 1.95-fold enhancement, improving from 4.81 pixels to 2.46 pixels.
