We developed a portable EO-COM based terahertz sensing system and evaluated the transmission characteristics of Yayoi pottery and Haji ware in the 300-GHz-band. By combining frequency-variable terahertz waves generated by the EO-COM with thickness corrections obtained through 3D scanning to calculate the attenuation coefficient, we found that Haji ware exhibited higher attenuation than Yayoi pottery. This method is expected to be applied to the non-destructive evaluation of cultural properties and outdoor measurements.
