Current fly-by-light (FBL) sensors represent a proliferation of different unique electro-optic interfaces and transducers. Development of standard electro-optic interfaces for diverse measurements (position, pressure, temperature, speed, etc.) offers potential to improve affordability of FBL sensor systems. Ladar fiber-optic sensor (LFOS) is a promising sensor technology that has demonstrated such a capability. A position transducer, temperature transducer, rotary speed transducer, liquid level transducer, and switch have all been demonstrated as plug compatible. In addition to providing a standard common interface, LFOS technology also offers the benefits of small and robust transducers, inherent multiplexing capability, and inherent fault detection and isolation capability. Current versions of the LFOS electro-optic interface consist of two VME circuit cards that are capable of interrogating and processing four multiplexed sensors. LFOS has been demonstrated in several flight and propulsion control laboratory testbeds. |
