摘要：
A system may include an LED array, an optical plane, optics, a sensor and a controller. The LED array is configured to generate LED light. The optical plane has a plurality of scattering features and with a mixing chamber. The optics is configured to direct the LED light to the optical plane. The plurality of scattering features are configured to reflect a sampled portion of the LED light into the mixing chamber. The mixing chamber is configured to mix the sampled portion of the LED light. The sensor is configured to sense the sampled portion of the LED light received from the mixing chamber. The controller is connected to the sensor and configured to control the LED array using the sensed, sampled portion of the LED light received from the mixing chamber.
