摘要 A system and method for projecting light including an arrangement for illuminating an array of digital micro-mirror devices with light; projecting light reflected by the array elements in an 'on' state thereof; and trapping light reflected by the array elements in an 'off' state thereof. The light trap is implemented with an anodized metal foam matrix. The matrix is secured relative to the array. The invention may be used in a variety of applications. In a digital light projector, a light source is included along with a prism and a projection lens. The metal foam matrix acts not only as a light trap but also as a heat-sink.
