Viscosity is an important parameter in fluid dynamics. Although many conventional techniques are useful in determining a limited range of liquid viscosity with high accuracy, non-invasive measurement techniques for a broader range of viscosity are yet to be developed. The subjects on viscosity are advancing rapidly partly due to the development and applications of microfluidic.
In anticipation of such developments, we are proposing a new method of viscosity measurement in the micrometer scale that is simple, non-invasive, real-time, wide dynamics range, and with imaging capability. This method relies on successful integration of laser scanning confocal microscopy, lock-in amplification, and variable galvono-scanning. It also has the potential to be a powerful tool in biology and medicine. The principle of operation is based on modulation microscopy that employs confocal configuration in detecting the deformation and phase delay of the forced oscillating sample.
