Abstract: A system for determining the concentration of an analyte in at least one body fluid in body tissue comprises an infrared light source, a body tissue interface, a detector, and a central processing unit. The body tissue interface is adapted to contact body tissue and to deliver light from the infrared light source to the contacted body tissue. The detector is adapted to receive spectral information corresponding to infrared light transmitted through the portion of body tissue being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information. The central processing unit is adapted to compare the electrical signal to an algorithm built upon correlation with the analyte in body fluid, the algorithm adapted to convert the received spectral information into the concentration of the analyte in at least one body fluid.

Abstract: A spectral image is corrected for optical aberrations. Tissue is exposed to a high-intensity, narrow band of light. The narrow band of light is scattered by at least one analyte in the tissue. Raman signals are optically collected from the scattered light. The Raman signals are directed to a wavelength-separating device. The Raman signals are detected as a function of intensity and wavelength to create the spectral image. The spectral image is corrected for optical aberrations using a software algorithm to spatially reassign intensity. The software may be adapted to use a reference image to make dynamic corrections. Fluorescence signals may also be collected.

Abstract: A method of obtaining a body fluid sample for determining the concentration of an analyte in the body fluid sample comprises applying pressure to the skin of the user. The skin is stretched so as to create a tear in the skin such that the applied pressure causes the body fluid to flow from the tear. The body fluid flowing from the tear is collected. Disclosed is also a pressure member for applying pressure to and stretching skin in preparation for forming a tear in the skin.
