All-optical complex field imaging using diffractive processors

Jingxi Li,
Yuhang Li,
Tianyi Gan
et al.

Abstract: Complex field imaging, which captures both the amplitude and phase information of input optical fields or objects, can offer rich structural insights into samples, such as their absorption and refractive index distributions. However, conventional image sensors are intensity-based and inherently lack the capability to directly measure the phase distribution of a field. This limitation can be overcome using interferometric or holographic methods, often supplemented by iterative phase retrieval algorithms, leadin… Show more
