Abstract

We show that using a simple two-beam coupling geometry and higher (non-Bragg) diffracted orders, one can obtain triple correlation between objects. The objects correlated here are microorganisms such as algae and can be used for identification of these microorganisms and their concentration in the solvent. The material used for correlation is a photorefractive organic polymer with no bias voltage.
