The objective of this Small Business Innovative Research (SBIR) Program is to develop a microtechnology based inline capable multi-tasked sensor for automotive fluidic analysis. Optical spectrometers can provide signatures of fluid absorption changes associated with contamination. Raman is a powerful analysis technique that uses optical reflection and optical spectra due to molecular vibrations providing information on the composition and chemical makeup of samples. Initial work on prototype gratings (key component) shows a device with resolution exceeding that necessary for optical and Raman spectrometry. Since the fluidic sampling, light source and microspectrometer can all be integrated on a chip in a sub centimeter sized package on one substrate, the device is expected to be very economical. Visca will develop ultra small microspectrometers on a chip that can be used for dual use for optical spectrometry and Raman spectrometry. A working prototype will be fabricated and tested during Phase II for evaluation in Department of Defense vehicles at Army TACOM. Visca will also design an integrated data acquisition and wireless data transmission system for the sensor. Finally, Visca will analyze the cost per unit to manufacture, cost savings to DoD, and the dual use applicability of the sensing system.
