Abstract
A method for manufacturing a broadband cholesteric polarizer includes positioning a layer of reactive material; irradiating the layer of reactive material; directing, at a first side of the layer, a monochromatic beam of light of a given wavelength toward the layer; and detecting, at a second side of said layer, a detected intensity of light of the given wavelength coming from the layer.

A method for manufacturing a broadband cholesteric polarizer comprising:
- positioning a layer of reactive material;
- irradiating said layer of reactive material;
- directing, at a first side of said layer, a monochromatic beam of light of a given wavelength toward said layer with a radiation profile whose intensity varies over the layer so that the layer is polymerized to an optically active layer of polymer material;
- and
- detecting, at a second side of said layer, a detected intensity of light of said given wavelength coming from said layer.
A method for manufacturing a broadband cholesteric polarizer comprising:
- positioning a layer of reactive material;
- irradiating said layer of reactive material;
- directing, at a first side of said layer, a monochromatic beam of light of a given wavelength toward said layer with a radiation profile whose intensity varies over the layer so that the layer is polymerized to an optically active layer of polymer material;
- and
- wherein said second side and said first side are at a same side, and a detecting act detects a detected intensity of light of said given wavelength reflected from said layer.
A method for manufacturing a broadband cholesteric polarizer comprising:
- passing a substrate through a radiation compartment;
- irradiating said substrate by an input radiation from a radiation source;
- directing, at a first side of said layer, a monochromatic beam of light of a given wavelength into said radiation compartment toward said substrate with a radiation profile whose intensity varies over the layer so that the layer is polymerized to an optically active layer of polymer material;
- and
- detecting, at a second side of said layer, a detected intensity of light of said given wavelength coming from said substrate.
