Paper Abstract

When an external electric field is applied, the write-in monochromatic and spatially incoherent intensity distribution received by a BSO crystal modulates its induced birefringence. The birefringence depends on the intensity distribution projected onto the crystal and the parameters like the thickness, applied voltage and rotatory power. In the reconstruction step, white light is employed and the birefringence modulation is transformed into a color modulation of the reconstructed image. On this basis it is analyzed the color feature of the image reconstructed. By employing a gray level transparency, it results several birefringence values each one associated to a determined write-in gray level.
