Abstract
Since the discovery of the wave behavior of light, diffraction has been a cornerstone in optics. The teaching of the diffraction theory has been usually done theoretically based on a mathematical approach that could hinder the understanding of the physical phenomena. In this work, the simplicity in the architecture of an accessible, cost-effective, and 3D-printed digital lensless holographic microscope is used as an educational tool to study the diffraction theory by providing experimental validations of the phenomena for undergraduate students. The recording and reconstruction steps of the lensless holographic technique take the students to the bidirectionally of the diffraction phenomena in a completely hands-on approach. The integration of the theory with an accessible experimental setup generates an innovative way of teaching the diffraction phenomena in a classroom.
