These patterns fall into three groups

a cluster

this is where the dots of us laser hitting the CCD are all bunched together. This would indicate that the CCD and the laser are in line with the motion either to or away from the direction of motion.

Spike

if the CCD rotates in such a fashion that the direction of motion crosses and edge of the CCD there will be a rapid leg up and when the CCD exactly points at the direction of motion the upward deflection will stop and then the spot will stay up until it encounters another force to change it. Say it finds the same body later as the planet rotates and sees the 2^nd body from the other side of the planet it is sitting on. the CCD passes the line of motion that will be a leg down resulting in a Spike formation. The spike is a rapid motion of the spot due to the geometry of the ccd late when the motion is in line with an edge there is more motion than if the motion detected is in front or behind the ccd

arc

if there is a gentle change in motion not involving straight on or straight away to the CCD and not involving an edge crossing there will be an arc of dots collected on the CCD these should be moving opposite to the actual motion detected. Ie if the sun say from earth is moving in an up and to the left motion then the recorded spots should be moving in a down and to the left motion.

Questions

In an idealized set up using a stationary velador what pattern of dots would be shown in a rising or setting sun with the ccd directly to or away from the sun ?

What pattern with a rising sun from the horizon to 50 deg elevation?

And what pattern when the sun say at noon crosses the edge of the ccd?
