Day 8

Today we worked on two things: Measuring the output of the photon detector with a Parallax USB oscilloscope and gnu radio, and programming and testing the sensor platform. The program is fairly simple: we go slowly forward, then rewind at normal speed to test again.

This picture is the response of the detector after a photon is detected; the red is what we're looking at.


This is a photon train; you can see 11 photons.


This is a high resolution shot of a photon. I want to learn more about the part happening before the peak; notice how there is a bounce.


Finally we are ready to collect our first readings! We plan on collecting them tomorrow. So check back tomorrow for the initial results.
