Ghost imaging is an optical technique in which the information of an object is encoded in the correlation of the intensity fluctuations of light. The computational version of this fascinating phenomenon emulates, offline, the optical propagation through the reference arm, enabling 3D visualization of a complex object whose transmitted light is measured by a bucket detector. In this Letter, we show how computational ghost imaging can be used to encrypt and transmit object information to a remote party. Important features, such as key compressibility and vulnerability to eavesdropping, are experimentally analyzed.
鬼成像技术是一种光学技术，其中物体的信息被编码在光强度波动的相关性中。这种迷人现象的计算版本模拟了参考臂中光的光学传播，从而可以对通过桶探测器测量的复杂物体的透射光进行 3D 可视化。在这封信件中，我们展示了如何使用计算鬼成像技术来加密和传输物体信息到远程方。实验分析了重要的特征，如密钥可压缩性和对窃听的脆弱性。
