Anamorphic optical transformation of an amplitude spatial light modulator to a complex spatial light modulator with square pixels [invited].
A method is proposed for the construction of a square pixel complex spatial light modulator (SLM) from a commercial oblong full-high-definition (full-HD) amplitude SLM using an anamorphic optical filter. In the proposed scheme, one half-band of the optical Fourier transform of the amplitude-only spatial light field is rejected in the optical Fourier plane and the other half-band is reformatted ...

متن کاملAnalysis of Modulator Circuits Based on Multi-dimensional Fourier Transformation
There are many communication circuits driven by multitone signals such as modulator and mixer. If the input frequency components are largely dHferent in each other, the brute force numerical method will take an enormous comput at ion time to get the steady-state responses. In this paper, we show a SPICE oriented algorithm based on multi-dimensional Fourier transformation, where all of the circu...
متن کاملMulticriteria characterization of coding domains with optimal Fourier spatial light modulator filters.
A multicriteria optimization method is introduced in order to find optimal filters for implementation on arbitrary spatial light modulators in the Fourier plane of an optical correlator. This method is applied to the trade-offs between noise robustness, sharpness of the correlation peak, and optical efficiency. A fast and simple algorithm is given in this case, which is independent of the parti...
