摘要： The radiance of a laser is a function of drive current. The radiance is also a function of other factors, such as age and temperature. A laser projection device adjusts laser drive parameters using a gradient descent operation. The device parameters may be adjusted iteratively and periodically. The period may be shorter or longer than a scan line in a video image.

摘要： An imaging system (100) includes one or more light sources (101,102,103) configured to produce one or more light beams (104,105,106). An additional light source (111) produces an additional light beam (112), which may be a non-visible light beam like an infrared beam. A spatial light modulator (107) is configured to produce images (109) on a projection surface (110) by scanning the light beams and the additional light beam within an image cone (118) oriented in a first direction (119). A partial reflector (117) is disposed within the image cone (118) and is configured to pass at least a portion of the light beams and reflect at least a portion of the additional light beam within a second cone (120) oriented in a second direction (121).

摘要： An apparatus determines a cursor position in an illumination field of a projector. An obstruction is detected in the illumination field. The cursor position is determined as the point on the obstruction furthest from where the obstruction crosses a border of the illumination field.

摘要： A scanned light display system includes a light source operable to emit light and a curved mirror positioned to receive at least a portion of the light. The curved mirror is configured to substantially collimate the received light. The substantially collimated light is scanned to form an image by moving at least one of the light source and the curved mirror relative to each other. Alternatively, the scanned light display system includes a light source operable to emit light, a curved mirror positioned to receive some of the light, and an optical element positioned to receive light reflected from the curved mirror. The optical element is configured to substantially collimate the reflected light. The substantially collimated light is scanned to form an image by moving at least one of the light source, the curved mirror, and the optical element. Scanning mirror assemblies and methods of making are also disclosed.
