Application of heterodyne double pass interferometer on the readout sensor for a biochemical fluidic channel

The heterodyne interferometer using the double pass geometry of optical beams in the acousto-optic modulator (AOM) has been applied for measuring concentrations of ethylene glycol solution. Our preliminary studies show that 0.001% of ethylene glycol can be measured by using this new method.
