Applications of multichannel imaging spectrometer

Based on the unique properties of the Volume Phase Holographic (VPH) Grating, P&P Optica has developed a high-performance imaging spectrometer system that has many uses in biophotonic and other research. These fields include, but are not limited to, optical transillumination spectroscopy for breast cancer detection, photodynamic therapy and other medical optical imaging. Since the spectrometer is able to image multiple channels simultaneously, there are a multitude of non-biophotonic applications as well, including process control and particulate detection for environmental research. This paper will outline the unique properties of the spectrometer and why it is valuable for the above applications. The discussion will include information on what Volume Holographic Gratings are and how they allow for the separation of the input and imaging parts of a spectrometer system. The result is a fiber optic spectrometer with superior SNR and efficiency compared to most currently available instruments. The paper will also highlight research results that have obtained using the high-performance, multi-channel imaging spectrometer.
