Abstract

Un système de projection d'images comprend une source de lumière polarisée et un modulateur de lumière spatiale, comportant une couche d'alignement, dans lequel la lumière polarisée est alignée sur la couche d'alignement pour laisser passer la lumière sans polariseurs. Trois images de couleurs différentes peuvent être produites par trois sources de lumière polarisée (222A, 226A, 230A) séparées avec un modulateur de lumière correspondant superposé. Les sources de lumière peuvent être maintenues dans un état activé ou peuvent être séquencées à des énergies d'entrée élevées pendant de courts intervalles pour réduire les coûts d'énergie moyens. Un ensemble de microlasers (922) peut être couplé à un dispositif de formage de faisceaux (936) pour augmenter davantage la brillance de l'image. Le dispositif de formage de faisceaux peut comprendre une plaque de phase binaire pour modifier la forme et le profil d'intensité du faisceau lumineux de projection.
