A terahertz imaging system was built from commercially available hardware whose functionality was integrated through home-made software with the goal of building a terahertz imaging platform for which other terahertz technologies would be born out of. The core of the system is based on terahertz time domain spectroscopy; a technique in which terahertz radiation is generated and detected by optically gating an emitter and detector respectively. Terahertz images of common objects found in a laboratory were produced primarily to test and calibrate the system and a new modality for achieving three-dimensional terahertz imaging for systems setup in transmission geometry is proposed based on these images.
