Multi-spectral phase coherence

Multi-spectral phase coherence is a concept commonly used in fields like remote sensing, imaging, and spectroscopy. It refers to the coherent analysis of phase information across different spectral bands or wavelengths. Here's a breakdown of the main components of the concept: 1. **Multi-Spectral**: This term refers to the collection of data across multiple wavelengths or spectral bands. In remote sensing, for example, multi-spectral images are collected using sensors that capture light in various parts of the electromagnetic spectrum (e.g.
