Learned a little more about the LK-G32. It can be set up for spectral reflection or diffuse reflection. Spectral reflection is the perfect, mirror like reflection of light, where the angle the light hits the surface at is the angle it bounces off at. For Diffuse reflection, the light bounces off in a range of directions.
For diffuse reflection, the laser beam is perpendicular to the surface being measured. For specular reflection, you tilt the laser head so the beam is coming in at an angle. You also have to change the setting in the laser's controller to "mirror reflection".
Picked up some electronics for Brad from Jameco.
Dropped off car at Independence Acura to get fixed.
Worked a little bit on the frame for the Fast GVT. Ordered some pipe clamps that will hopefully work for 1" dia pipe.
Found out that the way we are calculating rejection ratio might not be correct since we scale the differenced output from the circuit.
