High Resolution Fiber Grating Sensor Interrogating System (GM8037)

UC INSTRUMENTS' GM8037 high resolution fiber grating sensor interrogating system is a PC-based, compact size, high power, high accuracy, large dynamic range FBG sensors interrogating system and high accuracy optical spectrum analyzing system. The system includes an external device, PC-based application software and optional high performance laptop. With a build-in tunable laser source and two channel photo detectors (no additional light source is required), the system can performance a high accuracy FBG sensors interrogating and optical spectrum analyzer. It can be used for a wide variety of fiber optic sensors. The system provides users with a complete understanding of how the spectral shape of the fiber Bragg grating sensors react to varying physical conditions- rather than only reporting shifts in central wavelengths. This instrument is used both as the first step in the development of high-volume custom sensing systems and in long term field measurements. Two sensor channels allow simultaneous interrogation of multiple sensors on two fibers or both channel analysis. Either channel can be used to interrogate gratings in transmission or reflection and the system can be adapted to many types of sensors. All data can be transferred to an external PC via RS232 or USB communication ports.

It is a low-cost, high performance fiber Bragg grating (FBG) interrogation systems for various engineering and civil applications. It features PC-based, high accuracy, large dynamic range FBG sensors measurement ability and accuracy optical spectrum analyzing ability.
