System and method of non-contact glucose sensing

A system of non-contact glucose sensing in a sample, comprising:

• (a) a broadband laser-driven light source, said light source situated at a distance of between 0.5 and 2 meters from said sample;
• (b) a first lens system for directing a light emitted from said light source toward said sample;
• (c) a second lens system for receiving at least a portion of light from said light source reflected from said sample;
• (d) a monochromator, said monochromator for receiving from said second lens system said at least a portion of light from said light source reflected from said sample and selectively passing to an output fewer than all of any wavelengths of light received from said second lens system;
• (e) a CCD device receiving said output of said monochromator and producing a measurement of light reflectance;
• and
• (f) a CPU in electronic communication with said CCD device, said CPU at least programmed to perform the steps comprising:
• (1) reading from said CCD device said measurement of light reflectance from said sample;
• and
• (2) using said read measurement of light reflectance to determine a glucose level in said sample.
