I am doing a project called "gravitational waves in the rubber universe" and am looking for a little help.
The idea is to make a cone shape from latex and roll a ball-bearing around it (a bit like those donation boxes where you put in a coin and it rolls around in circles until it falls in the hole at the middle). From this I need to measure the displacement of the latex at various points as the ball moves around.
This is where I have the problem of what method to use. A few ideas I've had are:
Laser: put a reflective foil on the rubber and shine the laser onto it and measure the change in reflected angle.
Utrasound: Have an ultrasound generatror/reciever above the latex to measure the change in distance between it and the rubber.
Anyone with a good idea or any improvements or information on the two ideas above please help
