Presentation Outline

1. What is a Fiber Optic Sensor?2. MR303 Linear Sensor System3. Sample Operation4. How does it work?5. Homing Concept6. Some Customer Applications

1. Principle Of Fiber Optic Sensors“Remote sensing and measuring of a physical quantity using

photonics for both sensing and transmission.”

Since most Fiber Optic Sensors are not of transducer(1) type they require an interrogator.

Sensor• Amplitude Modulator• Bragg Gratings• Interferometers• Spectrum Modulators• etc.

To operate as a conventional incremental encoder, the user connects the A B quadrature outputs to the encoder inputs of the servo drive. For position monitoring, a feature rich Modbus interface and software protocol is available. USB or RS232 interfacing can be accomplished with readily available converters.

Presentation Notes

To operate as a quasi-absolute linear encoder, the user can read the internal position counted via the Modbus/RS485 serial interface. Or via USB with a RS485-to-USB converter. For position monitoring, a feature rich Modbus interface and software protocol is available. USB or RS232 interfacing can be accomplished with readily available converters.

Presentation Notes

To automate this process, Micronor has developed a special “Homing” zone left or right of the film’s active area, similar to the Index on a conventional encoder.

In this example, the internal Preset Value will be set to 250.

A Reset command (via HOMING input or software) to the Controller will reset the Internal Position Counter to 250.

5. Some MR303 Customer Applications

Designed for use in environments where conventional electronics-based encoders and resolvers cannot be used. • MRI • Medical • Semiconductor Processing• Linear Actuators• Robotics

Presenter

Presentation Notes

For MRI and medical applications, the high precision and accuracy of the MR303 system can enhance the performance of existing MRI systems as well as enabling new MRI applications and medical devices.

Application: MRI Safe Medical Devices

Today’s clinical MRI systems operate at field strengths of 1.5T and 3T with research systems operating up to 10T. The presence of ferromagnetic materials represent an extreme “ballistic” danger while non-ferromagnetic materials and metals can leave undesirable artifacts on MRI scans.

MRI Guided Prostrate Biopsies Help Quantify Risk and Detect More Aggressive Cancers

The increasing cost of cancer treatment has opened up creative opportunities for reliable methods for early detection.

Alternate detection methods have fairly high false-positive rates or can lead to incorrect analysis.

MRI-guided biopsy provides the most accurate results.
