More Information
Summary:An illumination system is disclosed, and such system may include a first light modulator (14) that modulates the phase of beamlets of light and generates phase modulated Gaussian beamlets of light (ABC), a light distributor (18) that transforms, the Gaussian beamlets of light to a homogenized rectangular pattern of light, and a second light modulator (56) that utilizes the phase modulated light to form an image. L'invention concerne un système d'éclairage, un tel système pouvant comprendre un premier modulateur de lumière (14) qui module la phase de petits faisceaux de lumière et qui génère des petits faisceaux (ABC) gaussiens modulés en phase de lumière, un distributeur de lumière (18) qui transforme les petits faisceaux gaussiens de lumière en un motif de lumière rectangulaire homogénéisé, et un second modulateur de lumière (58) qui utilise la lumière modulée en phase pour former une image.
