Abstract

The angular distribution of transmitted and reflected terahertz signal and the terahertz transmission and reflection spectra of human hard tissues (normal and with caries) were investigated. Characteristic terahertz absorption lines were found, which might allow diagnosing the disease oninitiatory stages. The carious spot increases the reflectivity of the terahertz signal, which provides a unique opportunity to diagnose caries quite accurate in vivo on initiatorystages.
