City sewers are huge, but the pipes that lead from homes and buildings are not. In most cases where a homeowner or building owner needs to see what and why their pipes are blocked or not functioning properly, the plumber uses a pipe inspection camera to get a good view. While this is perfect for all smaller pipes, you may be wondering why anyone would even attempt to use these small cameras in the much larger city sewer pipes.
If you've thought about going into the field of technology, you'll be learning a lot about piezo actuators and fast steering mirrors. The one thing you'll learn is that piezo actuators don't reach their maximum potential without the work of fast steering mirrors. That's because those fast steering mirrors allow laser beams to be moved, positioned, and repositioned quickly and accurately, which is crucial to the performance of your piezo actuator.
