Laser projection white balance tracking |
摘要 |
The radiance of a laser diode is a function of laser diode drive current. The radiance is also a function of other factors, such as age and temperature. A laser projection device includes laser diodes to generate light in response to a commanded radiance, and also includes photodetectors to provide a measured radiance. The commanded radiance and measured radiance are compared, and drive currents for the laser diodes are adjusted to provide luminance and color balance tracking.
