A method, computer program product and system for analyzing multispectral images from a plurality of regions of birefringent material, such as a polymer film, using polarized light and a corresponding polar analyzer to identify differential strain in the birefringent material. For example, the birefringement material may be low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyvinylidene chloride, polyester, nylon, or cellophane film. Optionally, the method includes generating a real-time quantitative strain map.

Detecting strain in birefringent materials using spectral polarimetry

A projection device having a coherent light beam-generator that generates a light beam and a beam expander disposed to receive the light beam and to emit an expanded light beam. The projection device also includes a digital micro-mirror device disposed to receive a holographic transform of an original image and to display the holographic transform for illumination by the expanded light beam into a holographic light beam with a convergent or focusing lens disposed to receive and modulate the holographic light beam and a liquid crystal plate volumetric image reconstructor that receives the focused holographic light beam and emits a 3-dimensional holographic image of the original image.
