Result When the radiated power was about a milliwatt ( mW) and detection range was up to 3 meters, the experimental results showed that this system can well detect the heartbeat and respiration signals from human subjects through common clothes and quilts. 结果在3m距离内,发射功率为1mW的条件下,可以穿透被褥、各类质地衣服检测到人体的呼吸、心跳信号。
We have firstly developed the all fiber femto-second laser, but its average output power is only tens of milliwatt. With the development of cladding pumped technology, it is the efficient way to amplifying the output power. 在国内我们已经首先研制成功了全光纤飞秒激光器,但平均输出功率只有几十毫瓦,包层泵浦技术的成熟,无疑给其进一步放大功率提供了技术保障。
