SPIE--International Society for Optics and Photonics Jul 31 2025 Skin cancer is the most common form of cancer worldwide, and early detection is key to successful treatment. While traditional methods rely on visual inspection and biopsy, researchers are developing new technologies that can provide more detailed information without cutting into the skin. A recent study published in the Journal of Biomedical Optics introduces a compact, noninvasive imaging system that combines two advanced
