Laser diode self-mixing: Range-finding and sub-micron vibration measurement
推荐理由
a pretty cool video where he demonstrates how a single laser diode can be used to measure miniscule vibrations
说明
这是2018年由Applied Science发布的一部演示,主题归在Electronics & circuit design。它讲的是laser self-mixing interferometry这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Ben Krasnow of Applied Science shows that a plain laser diode can measure sub-micron vibrations from centimeters away using self-mixing interferometry, and can also be used for range-finding.这些读者给出的理由,核心是:HN points to it as a cool demonstration of cheap precision laser measurement and the origin of hacks based on self-mixing.讲法不绑某一条新闻,过几年仍然可以当材料看。从2019年到2025年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义,就把注意力放在它怎么把laser self-mixing interferometry变成能跟着复述的例子。
