Terahertz endoscopy through a laser-driven terahertz source and detector

摘要

A terahertz imaging system for endoscopy is provided. The terahertz imaging system can be used when scanning tissue. A terahertz imaging system, according to embodiments of the present invention, can include a terahertz source, a terahertz detector, and / or a rotating element. The terahertz source can have plasmon contact electrodes that generate terahertz radiation and can be illuminated by an optical pump beam. The terahertz detector can receive terahertz field data. Terahertz sources and detectors can be arranged in an array. The rotating element can be a mirror mounted at a specific angle on the micromotor. The terahertz source, the rotating element, and the terahertz detector can be arranged in the catheter.
