Navy Continues Contract to Fund Development
of a Fiber Optic Vector Sensor

- March 17, 2010

The US Navy awarded VIP Sensors a third round of funding contract to develop a Fiber Optic Vector Sensor (FOVS) for thin-line towed sonar array applications, capable of left/right bearing resolution and depression/elevation angle determination in littoral and deep water operations.

The FOVS is a fully passive sensor, immune to EMI/RFI noise, and survives immerged pressures up to 2,500 PSI. Its design is conducive to form large arrays of vector sensors interconnected by a single common optic fiber. It allows the formation of more reliable and higher performance, thin-line towed sonar arrays. The FOVS are inherently self identifiable; the interrogation system knows what data belongs to what sensor.

The FOVS consists of a triaxial optical accelerometer and an optical hydrophone operating at different frequency bands. The excitation broad band light is returned with all four sensorsí information in a wave division multiplexing fashion. The fringe frequency peak variation is directly proportional to the measurand. The detection scheme for array applications is based on time division multiplexing of each vector sensor and on WDM of each of the four transducers of a temporally selected vector sensor.

VIP Sensorsí FOVS unmatched performance regarding small size, low mass, low noise, high sensitivity, and high frequency response, is based on patented EFP optical technology.

NASA Awards SBIR Contract to Develop
a Fiber Optic Pressure Sensor Array

- February 2, 2010

NASA awarded VIP Sensors a contract to develop a Fiber Optic Pressure Sensor Array for measuring air flow pressure at multiple points on flat surfaces of aircrafts for flight and wind tunnel test applications. The array consists of multiple micro-miniature optical MEMS pressure sensors interconnected by a common optic fiber to an interrogation system.

VIPís optical pressure sensors are essentially flat, light weight, fully passive (no electrical power), and EMI/RFI immune. They exhibit superior performance regarding accuracy, dynamic range and noise. They are inherently self identifiable; the interrogation system knows what data belongs to what sensor.

The proposed sensor array technology is applicable to different types of optical sensors (accelerometers, strain, temperature, etc). Each sensor in the array is designed to work at preset optical wavelengths; they are read by the interrogation system using Wave Division and/or Time Division Multiplexing.

VIPís Fiber Optic sensor array system not only has the potential to significantly improve pressure measurements for fight and wind tunnel testing, but its novel patented technology of micro-miniature networking optical sensors will benefit many other testing and monitoring applications.
