Before we start…
What is a diffuse reflectance spectroscopy?
Diffuse reflectance spectroscopy is a non-invasive spectroscopic technique for studying the optical properties of a biological tissue and hence can be used to detect chromophore concentration from the skin tissue.
How you do that?
The device contains an optical head that is easier to manufacture, more compact and more affordable than the existing fiber probes. This optical head consists of 19 fiber cables. The outer 12 fiber cables are used to expose the skin surface with a white light produced by a LED. And the reflected light emerging from the various layers of the tissue is collected by the inner 7 fiber cables, which is coupled to a spectrometer.
Why would you need this?
The diffuse reflectance spectroscopy can provide relevant clinical information such as total hemoglobin content, tissue oxygen saturation, oxy- and deoxyhemoglobin, lipid, and water content, and tissue scattering properties, and can thus be applied to monitoring tumor response to therapy. All important to keep your or your client’s health in the most optimal conditions.
