1) Optics and sensing technologies are becoming more portable and miniaturized, allowing for new diagnostic tools. 2) Spectrometers, sensors, and add-ons are entering the consumer market and have potential diagnostic applications by analyzing things like optical absorption, Raman signals, and THz signals. 3) This could enable new portable devices that provide basic health insights by examining things like the eye, which can provide clues about systemic conditions.
