什么是PWM? Click here to learn What is PWM 我不是专业人士，可以用一种简单的方式告诉我什么是PWM吗？ 首先，你需要知道，在TTL引脚输入直流0~2V电压会让激光器完全关闭，输入直流2.5V电压会让激光器全功率工作，输入直流5V也会让激光全功率工作，输入直流12V也会让激光全功率工作。 那么TTL上电压高低对输出功率有影响吗？ 没有，输入TTL的电压只会决定激光驱动器开启和关闭，0~2V是完全关闭，2.5V~12V完全开启，没有中间态，要么是完全开启，要么是完全关闭。 那么怎么做到50%功率输出呢？ 例子：用5V输入到TTL 1毫秒，然后用0V输入到TTL 1毫秒，循环往复，一秒会重复 1000 / (1+1) = 500次。 一秒重复500次？这能办到吗？ 人工操作不可能，但是使用微控制器可以很轻松办到，使用微控制器可以做到20000次每秒甚至更多。 你会看见激光闪烁吗？ 不会，人眼对30Hz以下的闪烁敏感，你看不到500Hz的闪烁，就感觉激光模组在持续输出功率一样（但是功率减半） 如何计算输出功率呢？ 在上面的例子中：ON Time / (ON Time + OFF Time) = 1 / (1 + 1 ) = 50% 如何改变输出功率呢？ 尝试改变输入5V的时间与输入0V时间的比值，功率输出 = 输入5V时间 / （输入5V时间+输入0V时间） 上面例子的PWM参数是？ 参数？这可能有点枯燥，但是不难，了解了之后会对我们接下在的学习提供帮助。 频率(f) = 1000毫秒 /
