I have to determine the best type of sensor to use to find the time interval in which a metal rod drops about about 1 foot. The sensor can't have any physical contact to the free falling object. The sensor can't be directly above or below the object
I've looked at maybe putting a series of Photo Reflective Sensors on top of each other. These would be located to the side of the falling metal rod.
I have also looked into Laser Interferometer but found my knowledge is very limited to how these work. I haven't been able to find much useful information on the internet about them yet.
I wondering if any one had any information or resources i could look at for more in-depth look at a variety sensor. Or if any one has suggestions on type of sensors i should be looking at.
If anything is unclear, please ask!
