Optical Properties of Skin
Human skin exhibit different optical properties depnding on the wavelength of the electromagnetic wave under study. The properties can even change because they are highly dependent on the hydration and thickness of the skin sample.

A zone plate can focus light using Fresnel diffraction instead of refraction. It is made on a small piece of transparent material such as glass or plastic and has concentric opaque circles printed onto the plate. These plates are placed so that the inference of the light creates zones of constuctive inteference. Ways of making your own plate.
Some math behind Fresnel zone plates
Hyperspectral Imaging collects the spectrum of an object or an area in many bands which can result in high resolution images. These high resolution images would be useful for agriculture, mining, and contractors when large areas of land need to be surveyed for composition.
There are four basic ways of hyperspectral imaging or HSI: spatial scanning, spectral scanning, non-scanning, and spatio-spectral scanning.

Spectroscopy studies the intereaction between matter and radiated energy as a function of wavelength. Spectroscopy is useful when finding the composition of an object because different elements have different spectra. Spectroscopy using a sample of rubdium and a diode laser has been done several times in the LTC, for example Bob Azmoun and Susan Metz did an intensive study of it.
