Over the past several decades, nonstationary optics has risen as a key enabling technology
for a multitude of novel applications. These include areas of research such as …

The notions of cross-spectral purity and spectral invariance of light impose specific
structures for the field coherence. Such concepts were originally introduced for stationary …

In this paper, we demonstrate that the vector light field is cross-spectrally pure if it passes
through two diffusers (having similar correlation properties) moving with identical linear …

We establish the concept of cross-spectral purity for nonstationary electromagnetic fields
having any degree of coherence or polarization. The conditions of cross-spectral purity in all …

This study establishes a reduction formula for nonstationary cross-spectrally pure vector (or
electromagnetic) light fields with any spectral bandwidth. In general, for nonstationary cross …

We consider the spectral spatial coherence characteristics of scalar light fields in second-
harmonic generation in an optically non-linear medium. Specifically, we take the …

This thesis contains theoretical and experimental studies on coherence, polarization, and
cross-spectral purity of vector light fields. We first develop and characterize a source having …

This thesis contains research related to random light fields. In particular, novel constructions
of electromagnetic coherence in beam fields are introduced, and certain fundamental …

We present optical systems, which transform isodiffracting nonstationary beams into fields
obeying either cross-spectral purity or spectral invariance. The designs are hybrid refractive …

The true nature of light has upheld the curiosity of mankind for centuries. According to the
current picture, light behaves as a wave but the explanation of some phenomena exclusively …
