“How can we produce a controlled chromatic aberration for study?”
Chromatic aberration is one of the most perplexing phenomena in the study of optics. However, creating controllable versions for laboratory study are extremely difficult to accomplish. So how can we make a machine that will be able to make adjustable chromatic aberrations at our will? Well, let’s use our engineering mindset to solve this scientific problem. Well, we know that if we were to pass monochromatic light into transparent glass at an angle then some will be reflected and some will be refracted. This creates two beams of light of identical wavelength for us to study. Now, let’s take this a step further. We need to pass these beams of light back to each other so that they interfere, which can be accomplished by placing mirrors in the path of beams. So what if were to take this system and bring it into a reality? This machine is known as an interferometer, and is used in physics labs all over the world to study the intricacies of chromatic aberration.
