By studying the traditional spectral reflectance reconstruction method, spectral reflectance and the relative spectral power distribution of a lighting source are sparsely decomposed, and the orthogonal property of the principal component orthogonal basis...

A method is presented for one-to-many information encryption transmission by using temporal ghost imaging and code division multiple access. In the encryption transmission process, code division multiple access technologies combine multiple information so...

Airy optical beams have emerged to hold enormous theoretical and experimental research interest due to their outstanding characteristics. Conventional approaches suffer from bulky and costly systems, as well as poor phase discretization. The newly develop...
