Summary A polarized light imaging technique is introduced that simultaneously captures and unfolds transmittance, fast/slow axes directions and birefringence or linear dichroism from single camera exposures. The technique, based on the rotating polarizer method, is capable of sampling an object through polarizers at four different angles in a single image with the use of an image multiplexer. The range of possible applications is demonstrated with examples from the fields of biology, medicine, forensics and material sciences.
