Application of Physics and Optics to Graft Dissection

Nanotechnology is a field of science that involves the application of light waves, which are measured in nanometers. Light can be used for many applications such as scanning your products at a supermarket. This can assist with inventory control and pricing. Another application of light is at the airport gate where your ticket and seat assignment are verified. Manufacturers and industrialists use light to produce accurate and reproducible products. Light can be used to measure pollution, map the DNA code, or produce a light show. These are but a few of the many beneficial uses of light. Their application falls under a growing field of engineering called optics.

An understanding of light and optics can improve many other scientific endeavors, as well. In medicine, we use light to remove pigmented lesions, smooth skin surfaces, remove hair, and evaluate tiny cracks or crevasses on the human body. In hair restoration surgey, we have found that polarized light improves the visualization of hair and green light accentuates the openings we make in the skin by making the openings appear black. We have also found that the principals of refraction, color addition, color subtraction, diffraction, and reflection help to improve the visualization of white hairs. All these principals involve the science of nanotechnology and are inherently important to the field of hair restoration surgery.
