This report takes a look into the patenting activity around fiber optic sensors uncovering the companies, inventors, intellectual property trends and other key indicators. Fiber optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors").
This report graphically analyzes fiber optic sensor markets from many perspectives, categorizes and highlights the key companies involved, defines unique keywords. This report also covers the global fiber optic sensors marketplace. It focuses particularly on the markets and opportunities for fiber optic sensors in defense, oil and gas exploration and drilling, medical, and industrial markets. The study considers future opportunities for new application markets.
This report was prepared by mining patent data using Patent iNSIGHT Pro, a comprehensive patent analysis platform that helps one accelerate time-to-decision from patent analysis activities.

    • Technology Insight Report FIBER OPTIC SENSORS A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing. Depending on the application, fiber may be used because of its small size, or the fact that no electrical power is needed at the remote location, or because many sensors can be multiplexed along the length of a fiber by using different wavelengths of light for each sensor, or by sensing the time delay as light passes along the fiber through each sensor. Time delay can be determined using a device such as an optical time-domain reflectometer. This report takes a look into the patenting activity around fiber optic sensors uncovering the inventors, patents, the companies and the intellectual property history behind these devices.Disclaimer: This report should not be construed as business advice and the insights are not to be used as the basisfor investment or business decisions of any kind without your own research and validation.

    • Brief History of Fiber Optic SensorFiber optics, though used extensively in the modern world, is a fairly simple and old technology.Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated byDaniel Colladon and Jacques Babinet in Paris in the early 1840s. John Tyndall included ademonstration of it in his public lectures in London a dozen years later.It was in the year 1956 that Kapany first officially introduced the term “fiber optics”. He defined fiberoptics as the art of the active and passive guidance of light, in the ultraviolet, visible, and infraredregions of the spectrum, along transparent fibers through predetermined paths. Since then, fiberoptics has been used in various photo-electronics devices, data processing, and photocopyingsystems. Today, optical fibers are primary components of global and local telecommunicationsystems. The primary method of transmitting information via optical fiber is digitally, that is, bysequences of optical pulses whose positions, widths, or occurrences can be modulated. The inventionof the laser in 1962 immediately stimulated a revolution that designers created fiber optic sensorscombining optical fibers and optoelectronic devices with the application of this coherent light source.Fiber optic sensors are attractive because they offer excellent sensitivity and dynamic range,compatibility with optical data transmission and processing, long lifetimes and potential, low cost andhigh reliability. They are immune to electromagnetic interference. Fiber optic sensors can also work inother hostile environments, where there may be high temperatures, high-voltage, corrosive materials,all-solid-state configurations, vibration and explosion hazards, and where traditional sensors andtransducers do not work well. The lightweight and small sizes of these devices are critical in such areasas aerospace and provide substantial advantages to many products. The comparable low cost isanother advantage of fiber optic sensors. With each new successful product the cost of existing andnewly introduced components continues to drop, opening the door for new waves of fiber sensorproducts. These developments include the replacement of conventional spinning mass-inertial sensorswith fiber optic gyros, widespread use of fiber optic sensors in process control and manufacturing,electrical isolation of patients in medicine, and fiber optic health monitoring systems in the aerospaceand construction industries. © 2011 Gridlogics.

    • Publication TrendWhat has been the IP publication trend for Fiber Optic Sensors?The patent publication trend in the form of a bar graph shows activity from as early as the 1960’sand 1970’s, although the number of filings remained relatively low all the way up till the year2000. From 2001 which saw a jump to 80 patents published, there was increase in number ofpublications from 2006 which saw more than 100 patents.It’s clear the current activity around these technologies is likely to continue seeing moreinnovation in the near future.How we did it?Once the patents were populated in Patent iNSIGHT Pro, the publication trend chart was generated on a singleclick using the dashboard tool. © 2011 Gridlogics.

    • Keywords vs. Fiber Optic Technologies – White Space AnalysisWhat are the top keywords in Fiber Optic technologies and how do they vary across the different fiberoptic sensor types? For this a cleaned list of keywords that were generated from the Title, Abstractand Claims. Such a table can be used for preliminary insights toward White Space Analysis. (White-spaces are gaps in a technology landscape that have potential for attaining exclusivity.)As can be seen in the table below the concept of “Electromagnetic Sensor”, “Displacement Sensor”haven’t been used in any of the Intrinsic and Extrinsic Fiber Optic Sensors. Such an indication can befurther verified via patent search to confirm existence of a white space. © 2011 Gridlogics. All Rights Reserved.
