TED: How we can use light to see deep inside our bodies and brains | Mary Lou Jepsen

The video explores the use of red and infrared light to improve healthcare by enabling non-invasive imaging of the human body. It demonstrates how light can pass through human tissue and bones, and how holography can be used to de-scatter light for clearer imaging. The technology allows for focusing light through brain tissue to a neuron, offering potential for portable, low-cost medical imaging. The video also discusses the use of sound and light for scanning, and highlights applications such as early cancer detection, stroke diagnosis, and brain-computer communication.
