OPPORTUNITY

In microscopy, fluorescence imaging, endoscopy and other biomedical imaging approaches, there is often the necessity to utilize multiple different wavelengths of light to detect various features of the sample or subject. This is often accomplished by switching between several filters or lasers, which makes it necessary to take multiple separate pictures. Combining multiple light sources into a single output would reduce scan time, which would improve system durability and reduce costs associated with instrument use. In addition, switching to light-emitting diodes (LEDs) would eliminate the need for expensive lasers or other conventional light sources.

BREAKTHROUGH IN SAMPLE ILLUMINATION FOR SPECTRAL IMAGING

Researchers at the University of South Alabama have developed a method and device for combining the output from many single-band light-emitting diode (LED) sources into a single output.  This technology allows for the selection and differentiation of a single LED output from the combined output.  Importantly, this technology utilizes an array of customized mirrors to co-align the output of multiple light sources.  In addition, this technology is capable of coupling the co-aligned output to a light guide (solid, liquid, fiber optic or similar) to facilitate the transmission of the co-aligned light output.  This technology is highly applicable to microscopy, fluorescence imaging, endoscopy and other biomedical imaging approaches.
