ABSTRACT
Research towards practical applications of ghost imaging attracts more and attention in recent years. Signal-to-noise ratio (SNR) bucket results thus quality images can be greatly affected by environmental noise, such as strong background light. We introduce temporal cross-correlation into typical to improve SNR value, taking profile illumination pulses a prior information. Experimental at sunny noontime verified our method, with the improved for object distance 1.3 km . also show possibility 3-dimensional imaging, experimentally.
