The FAZT FEMTOSENSE GATEWAY supervisory software is used for monitoring the performance of one or many interrogators, for recording their sensors’ data, and for storing and/or further distributing the data, as required by the application.

Designed with larger scale systems in mind, the FEMTOSENSE GATEWAY supports monitoring of up to eight (8) interrogators simultaneously. The software interfaces seamlessly to any interrogator model in the FAZT product family, including the “Workhorse” and OEM models.

The FEMTOSENSE GATEWAY software is an optional package available for optical sensing system architects and is particularly well fit for larger scale systems that require data collection and recording for hundreds (100’s) of sensors at scan rates of up to 8kHz. The FEMTOSENSE GATEWAY can connect to multiple interrogators in synchronous and asynchronous mode.


Enables large scale data management, storage and distribution of ultimate precision, repeatability and accuracy measurements: Our flagship FAZT I4G interrogator returns measurements in 1pm steps across its wavelength range. Using patented FAZ Technology scan-by-scan calibration, the instrument features ultimate 0.1pm absolute precision, superb repeatability of 50fm max, and absolute accuracy of 1pm (Gas Cell and MZI referenced in closed PM circuit). The FEMTOSENSE GATEWAY effectively manages the massive data that can be generated by one or many FAZT interrogators operating in parallel while deployed in larger scale systems and helps the customer analyze, store, and/or transmit the relevant information.

Reduces third party development time for OEM systems: A programming interface is provided to allow integration of the FEMTOSENSE GATEWAY with third party software.

World-Class Applications Engineering Support: Experienced design, configuration, field installation, and data management/interpretation engineers from Femto Sensing International, FAZ Technology and Fugro are available to provide applications specific customer support from optical sensors selection to sensing arrays configuration and installation, from interrogators selection to configuration and operation, from data management for small dedicated systems to large scale monitoring system architectures.
