摘要 |
<p>A propagation measuring apparatus for measuring propagation characteristics of an object to be measured includes a first light source for outputting a first optical signal of a first frequency, a second light source for outputting a second optical signal of a second frequency, a terahertz light outputting unit for generating terahertz light of a frequency, which is equal to a difference between the first and second frequencies, by using the first and second optical signals and radiating the terahertz light to the object to be measured, a first detecting unit for detecting the terahertz light passing through the object to be measured and a measuring unit for measuring the propagation characteristics of the object to be measured based on the terahertz light detected by the first detecting unit.</p> |
