✨ How do scientists measure extremely weak light signals?
🔎 One powerful technique is Optical Heterodyne Detection.
🪄 By mixing a weak optical signal with a strong reference laser, researchers create an interference beat signal that makes tiny frequency, phase, and amplitude changes measurable.
📝 This technique plays a central role in quantum optics, optical communication, laser metrology, and precision sensing.
