Abstract
The theory of modulation of spatial coherence of optical field with the aid of a dynamic diffusion screen is given. Some useful models of a random phase screen are considered. The possibility of modulation of spatial coherence by means of liquid crystal light modulator is demonstrated with a physical experiment.
Keywords: Cross-spectral density; spatial coherence; random phase screen; liquid crystal light modulator.
Resumen
Se da la teoría de la modulación de coherencia espacial de un campo óptico por medio de una pantalla de difusión dinámica. Se consideran algunos modelos útiles de la pantalla de fase aleatoria. La posibilidad de la modulación de coherencia espacial se demuestra con un experimento físico.
Descriptores: Densidad espectral cruzada; coherencia espacial; pantalla de fase aleatoria; modulador de luz de cristal líquido.
