Title: | Optical information authentication using phase-only patterns with single-pixel optical detection | Authors: | Xiao, Y Zhou, L Chen, W |
Issue Date: | 1-Apr-2021 | Source: | Applied optics, 1 Apr. 2021, v. 60, no. 10, p. B1-B7 | Abstract: | In this paper, we propose and experimentally demonstrate phase-only authentication based on single-pixel optical imaging through scattering media. The propagating wave is sequentially modulated by using a series of random amplitude-only patterns embedded in a spatial light modulator (SLM), and then a series of one-dimensional (1D) intensity values is recorded by the single-pixel (bucket) detector. Subsequently, an intensity pattern just before the SLMis retrieved by using a correlation algorithm and then further propagates back to the object plane in which the object phase pattern is recovered to serve as reference. Then some single-pixel intensity values are randomly selected from the recorded data, and 1-bit compression is applied to the randomly selected data in order to generate 1D binary signals as ciphertext. A series of random amplitude-only patterns corresponding to the randomly selected single-pixel intensity values serve as principal keys. In a scattering environment, the proposed method is able to carry out phase-only authentication without visually rendering the plaintext, which has not been previously studied. It is found that phase-only authentication is sensitive to security keys, and the proposed method possesses high security. In addition, the proposed method is highly robust to noise contamination and data-loss contamination. Optical experimental results demonstrate the feasibility and effectiveness of the proposed method. | Publisher: | Optical Society of America | Journal: | Applied optics | ISSN: | 1559-128X | EISSN: | 2155-3165 | DOI: | 10.1364/AO.414419 | Rights: | © 2021 Optical Society of America.
