MTI-2100 FotonicTM Sensor Unmatched Resolution and Frequency Response in Non-Contact, Fiber-Optic Measurement The MTI-2100 features advanced fiber-optic and electronic technologies for precise measurements of displacement, position and vibration. It sets new performance standards with resolution as low as 0.01 µin. (2.5 angstroms) and frequency response from direct-coupled (dc) to 500 kHz. The MTI-2100’s modular design has the flexibility to be tailored to specific requirements through the Dual-channel capability enables the user to make use of a wide range of interchangeable and custom...

Standard Fotonic Probe Operating Principle Each MTI-2100 Fotonic probe contains a signal of zero. As the probe-to-target set of light transmitting and light receiving distance increases, increasing amounts fibers, which can be arranged in three differ- of light are proportionally captured by ent configurations (random, hemispherical the receive fibers. The result is a very or concentric). A tungsten halogen lamp sensitive, linear output response Optical Peak feeds light down the transmit fibers, distance is further increased, the amount target. Light that is reflected from the is reached, a...

Reflectance Compensated Fotonic Probe probe module’s electronics use the differ- that automatically compensates for large ence between the two receive bundles to changes in reflectivity of the target being compensate for reflectivity changes and measured. This unique design makes it provide a linear response proportional possible to monitor targets over a dynamic to probe gap. This concept allows the reflectance range of 100:1, while main- taining high resolution and accuracy. where the target is translating or rotating. The probe consists of three integrated Output Voltage MTI also offers...
