No, removing the barrier mirror should not be allowed. If you're having trouble measuring the barrier mirror's angle because it moves, you're probably allowed to just hold it in place so that it doesn't move. It should be especially easy if the LSS has a magnetic surface to hold the mirrors in place. If it's hard to put a protractor on the surface of the LSS because other mirrors are in the way, you can just place it on top of the barrier mirror, making sure not to move it. I've seen a lot of people use protractors with strings attached to them to help them measure the angles.anug123 wrote:Is it allow to replace barrier position with some laminated cutout and put them back after determining all position of mirrors? I feel it is very hard to measure the angle of barriers mirrors, with keeping the wooden block.
Any other suggestion you folks have that would help if we want to strike the barrier mirror which become crucial to get good scores in LSS.
Also, I heard next year, optics is going away, any idea with which event this would be replacing?
Next year, optics should be replaced by circuit lab.
Hope that helped!
