Abstract
The present disclosure provides a method of analyzing an area of interest of a sample material which comprises directing a first radiation to a first area of interest, the first radiation having frequencies within a terahertz frequency range. The method also comprises receiving a first signal THz1 being a quantity related to radiation received from the first area of interest in response to directing the first radiation to the first area of interest, the first signal THz1 being dependent on a first property and on a second property of the first area of interest. Further, the method comprises directing a second radiation to the first area of interest, the second radiation having frequencies within a frequency range that is different to that of the first radiation. In addition, the method comprises receiving a second signal IR1 being a quantity related to radiation received from the first area interest in response to directing the second radiation to the first area of interest, the second signal IR1 being dependent on the second property of the first area of interest. The method also comprises scaling or co-registering times of flight associated with the first signal THz1 and the seco…
