Technology Overview: Principles of Terahertz Hyperspectral Imaging

Terahertz hyperspectral imaging (THz-HSI) systems represent a convergence of terahertz (THz) spectroscopy and advanced imaging technologies, enabling the acquisition of spatially resolved spectral information in the 0.1–10 THz frequency range. The core principle involves illuminating a sample with broadband or tunable THz radiation and capturing the transmitted or reflected signals across multiple spatial points, generating a three-dimensional data cube (x, y, frequency). This approach allows for the identification and mapping of chemical, physical, and structural properties that are often invisible to conventional optical or infrared imaging.

In 2025, THz-HSI systems are primarily based on two technological platforms: time-domain spectroscopy (TDS) and frequency-domain spectroscopy (FDS). TDS systems utilize ultrafast pulsed lasers to generate and detect short bursts of THz radiation, providing both amplitude and phase information. FDS systems, on the other hand, employ continuous-wave sources, such as photomixers or electronic multipliers, to scan across discrete frequencies. Both approaches are being refined for higher sensitivity, faster acquisition, and improved spatial resolution.

Key hardware components include THz sources, detectors, and optical elements. Leading manufacturers such as TOPTICA Photonics and Menlo Systems are advancing compact, fiber-coupled THz emitters and receivers, with a focus on turnkey integration and robustness for industrial and laboratory environments.
