Raman spectroscopy, a non-destructive optical technique, probes the vibrational modes of materials by measuring the inelastic scattering of monochromatic light, typically from a laser. This powerful method provides essential chemical and structural information, including molecular composition, crystal quality, and insights into stress or strain in materials. Widely utilized in semiconductor research, 2D materials, and nanomaterials, Raman spectroscopy is valued for its high spatial resolution and its capability for optical imaging, allowing for analysis of samples without special preparation.

Non-destructive optical techniques like optical imaging capture high-resolution images of samples using visible light and microscopes, often at multiple fields of view to encompass large areas. Image stitching merges these overlapping images into a single seamless composite, allowing for detailed analysis of the entire sample. Tools such 

Non-destructive optical techniques like optical imaging capture high-resolution images of samples using visible light and microscopes, often at multiple fields of view to encompass large areas. Image stitching merges these overlapping images into a single seamless composite, allowing for detailed analysis of the entire sample. Tools such as ImageJ are then utilized to quantify features like size, area, intensity, or particle count, providing a robust and flexible platform for both qualitative and quantitative analysis in materials science, biology, and microfabrication. Additionally, Raman spectroscopy can complement these methods by offering insights into the molecular composition of the samples.
