  1. Assuming the surface to be a mirror reflection(theta1 = theta2). Need an equation when varied the incident angles we would obtain the second reflection angles or a method to do so. please view the image for better understanding. The pyramids are equally spaced of equal height and equal base length and same level(can also assume more number of pyramids in the x and y directions making z to be the height). The angle of the pyramid can be a assumed(like 60 degree). The given data is the first angles of incidence and reflection(assuming mirror reflection). the unknown value is the second angles
  2. I am looking for some mirror setup where rotation one or more elements in the mirror setup will allow to shift the beam along its axis. Two mirrors in a galvanometer scanner type setup work well for controlling the angle of the beam. Rotating risley prisms can be used to only offset the beam without changing its angle but the possible positions are limited. Dove prisms are great for rotating the beam along itself or rotate in a circular fashion if prism center is shifted. But as for offsetting (shifting) a beam along its axis from a (-1,-1) position to (1,1) without changing the angle of t
  3. I am supposed to shoot up a six-minute speech along with a presentation at a competition nearby. The topic is "Harnessing Light: Possibilities and Challenges" Therefore, my question is what do you think are the possibilities and challenges of harnessing light? I am supposed to stick to the topic entirely, and that is what makes it difficult. I would be glad if some knowledgeable person shares his/her knowledge and views! Thank you! :-)
