FAQ
What is Design Considerations of Fiber Optic Gyros?
Complete Inertial Measurement Units (IMU) to determine motion of a vehicle in three-dimensional space have as a minimum without redundancy six sensors, normally three linear accelerometers and three single axis gyros. Driving design parameters in the fïeld of sensor packages for avionics, flight control, and missile guidance are volume, power consumption, and also weight. Especially small size is often more important than an individual performance parameter.
Due to the modular structure of the FOG and especially as a result of the flexibility in design, shape, and size of the sensing coil, the size of the optical part of the FOG meets almost a11 requirements known for today’s rate gyro packages and IMUs.
In contrast to the small FOG optics is the electronics for a single axis FOG. Depending on performance, ASIC or hybrid implementation, available supply voltages, and interface features, it may have a size up to 100 x 150 mm printed circuit board. Power consumption of a complete FOG with a light source containing a thermo-electric cooler is temperaturedependent and is in the range of 5~12 W with the highest power consumption at the temperature extremes. Therefore new IMU designs are aimed at a reduction of size and power dissipation of the electronics rather than smaller optical modules. A size reduction can be obtained without changing the proven readout and signal processing schemes by higher integration of the electronics, e.g. digital and analog ASICs, three charme1 hybrids, external power conditioning, and tailoring for specific applications. A breakthrough however is only possible if multiplexed FOG triads are considered. In order to achieve an optimized multiple-axes FOG design with significantly reduced power consumption and minimum number of parts several steps are possible.
