The T‑Gauge® Control Unit (TCU) is the central component of the T‑Gauge® family of products and serves as the source of the optical and electrical signals necessary to generate and detect terahertz. The TCU also transforms analog data into a digital signal that can be analyzed using the onboard processor and interacts with the wide variety of THz accessories.
The TCU is a 19 inch (483 mm) rack, wall, or table mountable instrument, consisting of an ultrafast laser, high-speed optical delay, ranging optical delay, power supplies, and signal conditioning electronics, with connectors for convenient interfacing to various optical and electronic components. The high-speed delay included in the TCU can be chosen from a number of delay length and speed options. When utilized in conjunction with T-Gauge® accessories, the TCU enables the user to generate and detect pulsed terahertz energy for a wide variety of measurements.
