Fiber Optic Gyro for Land Navigation
Requirements for a gyroscope intended for use in land navigation in a coupled dead-reckoning/GPS are governed more by cost than by performance. As a result, explicit performance measures are poorly defined. The development of a low-cost fiber optic gyro for this application is described. Using openloop signal processing, a short coil length, and simple packaging concepts, it represents an evolu...
متن کاملSelf-calibration method based on navigation in high-precision inertial navigation system with fiber optic gyro
A rotary inertial navigation system requires higher calibration accuracy of some error parameters owing to rotation. Conventional multiposition and rotation calibration methods are limited, for they do not consider sensors’ actual operating condition. In order to achieve these parameters’ values as closely as possible to their true values in application, their influence on navigation is analyze...
متن کاملFiber optic immunochemical sensor for continuous, reversible measurement of phenytoin.
This fiber optic sensor, based on a homogeneous fluorescence energy-transfer immunoassay, operates in a continuous, reversible manner to quantify the anticonvulsant drug phenytoin. B-Phycoerythrin-phenytoin and Texas Red-labeled antibody to phenytoin were sealed inside a short length of cellulose dialysis tubing, which was cemented to the distal end of an optical fiber. When the sensor was alte...
متن کاملA New Open-Loop Fiber Optic Gyro Error Compensation Method Based on Angular Velocity Error Modeling
With the open-loop fiber optic gyro (OFOG) model, output voltage and angular velocity can effectively compensate OFOG errors. However, the model cannot reflect the characteristics of OFOG errors well when it comes to pretty large dynamic angular velocities. This paper puts forward a modeling scheme with OFOG output voltage u and temperature T as the input variables and angular velocity error Δω...
متن کاملMedical Smart Textiles Based on Fiber Optic Technology: An Overview
The growing interest in the development of smart textiles for medical applications is driven by the aim to increase the mobility of patients who need a continuous monitoring of such physiological parameters. At the same time, the use of fiber optic sensors (FOSs) is gaining large acceptance as an alternative to traditional electrical and mechanical sensors for the monitoring of thermal and mech...
