EMCORE DSP-1750 FOG (Non-ITAR)
REMCORE takes fiber optic gyro (FOG) technology to a new level of performance with the DSP-1750 FOG, the world's smallest high-accuracy FOG, available in both single-axis and dual-axis configurations.
Description
Overview
With the DSP-1750 FOG, the world’s smallest high-accuracy fiber optic gyroscope, EMCORE takes FOG technology to a new level of performance. Available in both single-axis and dual-axis configurations, the DSP-1750 FOG is designed for a wide range of precision navigation, stabilization, and pointing applications where low noise and high performance, across the entire range of operating temperatures, are critical. Ideal applications include long-range optical and sensor systems, gimbals, tactical missiles, autonomous vehicle navigation, and the stabilization of virtually all types of commercial equipment platforms.
The DSP-1750 FOG delivers performance never before achieved in FOGs of similar size. Utilizing EMCORE’s 170-micron E-Core ThinFiber, the world’s smallest D-shaped optical fiber, it delivers extremely low noise coupled with high bandwidth. This super-compact FOG offers superior performance in angle random walk and bias stability, as well as over shock and vibration.
Featuring a flexible design in which the optical sensor is separate from the control electronics, the DSP-1750 FOG has a 45.7 mm (1.8 in) diameter optical sensor housing connected to its power and processing electronics via a robust interlocking tether. This two-piece design allows the sensor to be installed directly on the sensitive axis, while the control circuit cards can be integrated elsewhere, such as in an existing board stack assembly. This innovative design makes the DSP-1750 FOG easy to integrate into customer platforms where space and payload weight are at a premium.
EMCORE is the only U.S. FOG manufacturer that draws its own optical fiber, ensuring consistent quality, performance, and instant turn-on to turn-on repeatability in every FOG. And like all of EMCORE’s precision FOGs, the solid state DSP-1750 FOG is built using EMCORE’s patented Digital Signal Processing (DSP) electronics design which offers significant improvements in such critical areas as scale factor and bias stability, scale factor non-linearity, and maximum input rate.
