Research Topics


Optiphase, Inc. proposes a highly innovative and unique approach to non-intrusive, non-contacting vibration sensing. This approach involves a fiber optic sensor implementation which opticaly performs differentiation of interferometric displacement data to obtain the desired velocity data. This completely unique approach is capable of providing accurate vibration measurements over ranges which significantly exceed that stated in the solicitation specification. During the preparation of the Phase I proposal, the proposed measurement concept was validated through laboratory experimentation. We propose, for Phase I to determine the feasibility of the proposed approach against the intended application, for hand held measurement of vibration data, inclusive of providing data storage and analysis. We expect to not only prove the feasibility, but to also show that the technology is manufacturable at half the cost of existing laser Doppler vibration systems without compromising measurement performance. In Phase II, we will develop and evaluate a prototype apparatus which accomplishes the solicitation objective. We expect a significant and immediate market for this innovative technology.
