用于激光二极管的控制设备、激光投影系统和用于在激光二极管中散斑减少的方法
摘要：
本发明涉及一种用于激光二极管(7)的控制设备(1)，所述控制设备具有第一驱动装置(3)和分析处理电路(2)，所述第一驱动装置设计用于产生经高频调制的控制信号(5a)并且为了抑制散斑将所述控制信号馈入所述激光二极管(7)中，所述分析处理电路与所述第一驱动装置(3)耦合，并且所述分析处理电路设计用于输出指示由所述激光二极管(7)发射的光的强度(7a)的强度信号(2b)并且根据所述强度信号(2b)向所述第一驱动装置输出调节信号(3a)来调节所述经高频调制的控制信号(5a)。
摘要（英）：

The invention relates to an actuation device (1) for a laser diode (7), comprising a first driver device (3) which is designed such as to generate a high-frequency modulated actuation signal (5a) and feed said signal into the laser diode (7) in order to suppress speckles, and comprising an evaluation circuit (2) which is coupled to the first driver device (3) and is designed such as to emit an intensity signal (2b), which indicates the intensity (7a) of the light emitted by the laser diode (7), and to emit a control signal (3a) to the first driver device (3) in order to control the high-frequency modulated actuation signal (5a) depending on the intensity signal (2b).
