A micro-optical-mechanical-electro-system (MOMES)-based non-invasive blood
glucose monitor comprises a micromachined infrared optical filter array, a
micromachined infrared mechanical modulator array, at least one
micromachined infrared tunable filter, and at least one infrared detector.
Each optical filter is aligned with a mechanical modulator along its
optical axis direction. The optical filter continuously divides a
monochromatic infrared light in a wavelength range within 0.8 to 25 micron
from an infrared light. The aligned mechanical modulator turns the
monochromatic infrared light into an alternating monochromatic infrared
light. The tunable filter is aligned with the infrared detector along its
optical axis direction. The tunable filter selects the back-diffused
alternating monochromatic infrared light emitted from a measured blood
subject that is illuminated by the alternating monochromatic infrared
light. The infrared detector converts the back-diffused alternating
monochromatic infrared light into an alternating electronic signal. Then a
photo-integrated circuit (IC) combines with the infrared detector for
synchronous detection and amplification of the electronic signal generated
by the synchronous detection.
