Wavefront analysis is a technique used in optics to measure and analyze the properties of light waves as they pass through or reflect off of various surfaces. By examining the shape and distortion of the wavefront, researchers can gain valuable insights into the quality of optical systems, such as lenses or mirrors, and how they affect the transmission of light. Wavefront analysis is often used in fields such as ophthalmology, astronomy, and microscopy to optimize and improve the performance of optical instruments.
