Simple BOCDR design maps strain and temperature along fibers without costly GHz equipment.

Osaka University researchers develop a novel microfluidic chip that can detect very small concentrations of dissolved contaminants using just 100-picoliter sized samples. By using a terahertz point source, the detection area can be made very small. This work may lead to lab-on-a-chip technology for environmental and health care monitoring.
