Phase-only optical filter for use in an optical correlation system |
摘要 |
A phase-only optical filter capable of being utilized within a phase-only optical correlation system. The phase-only optical filter is made by mathematically generating preselected phase-only information by a fast Fourier Transform technique. This generated phase-only information is transferred onto an unexposed holographic film. Thereafter, the film is developed and subsequently bleached. The resultant bleached film is the phase-only filter which, when utilized in a correlation system, provides substantially 100% utilization of the source of electromagnetic radiation during the correlation process.
