摘要

Abstract

Transparent objects are invisible to traditional cameras because they can only detect intensity fluctuations

necessitating the need for interferometry followed by computationally intensive digital image processing. Now it is shown that the necessary transformations can be performed optically by combining machine learning and diffractive optics

for a direct in-situ measurement of transparent objects with conventional cameras.
