The broad-band illumination challenge, i.e. to illuminate the sample under study with a
continuous broad-band spectrum, covering both the visible, near and shortwave infrared, one has to
rely on rather bulky and energy inefficient incandescent or halogen lamps.
The InSPECT project will address this challenge by developing and integrating photonic building
blocks for low-cost miniaturized spectral tissue sensing devices. This involves the realization of a miniature, broad-band, LED-based light source emitting in the visible, near and short-wave infrared (400-1700 nm) to be used for diffuse reflectance spectroscopy; based on wavelength up-conversion of LED emission in photoluminescent materials like phosphors and quantum dots.
