Title: | Ghost imaging for three-dimensional optical security | Authors: | Chen, W. Chen, X. |
Issue Date: | 25-Nov-2013 | Citation: | Chen, W., Chen, X. (2013-11-25). Ghost imaging for three-dimensional optical security. Applied Physics Letters 103 (22) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.4836995 | Abstract: | Ghost imaging has become increasingly popular in quantum and optical application fields. Here, we report three-dimensional (3D) optical security using ghost imaging. The series of random phase-only masks are sparsified, which are further converted into particle-like distributions placed in 3D space. We show that either an optical or digital approach can be employed for the encoding. The results illustrate that a larger key space can be generated due to the application of 3D space compared with previous works. © 2013 AIP Publishing LLC. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/56138 | ISSN: | 00036951 | DOI: | 10.1063/1.4836995 |
