FOTONIC EDGE FIBER-OPTIC PROBE
Custom fiber-optic probe designed to measure dynamic position of thin objects.
Measure Dynamic Edge Position, Displacement, Vibration or Runout at Speeds up to 150 kHz
The MTI-2000 Fotonic Edge Probe provides precise, accurate and repeatable measurements of displacement, runout and vibration of thin objects. The unique fiber optic probe design is unaffected by target reflectivity or shape, making it ideal for wide variety of applications such as computer disk drive runout, magnetic tape motion or ultrasonic tool vibration. The ultra-low noise characteristic of the Fotonic Edge Probe produces static and dynamic measurements with resolutions to 0.05 uin (1.25 nm).
The MTI-2100 provides outputs of peak-to-peak vibration and displacement via the digital display, analog dc voltage output or RS-232 computer interface. The dual channel design allows two probes to simultaneously measure displacements and vibrations at different target locations.
Along with its high sensitivity, the Fotonic Edge Probe is easier to set up and use than other techniques. It only takes a minute to position the probe and obtain accurate, high-resolution measurements. Custom designs are available to adapt to almost any application or space requirement.

The fiber optic probe directs a "curtain" of light past the measurement target edge to an opposing receive fiber bundle. As the target moves within this "curtain", the intensity of light received changes proportionally with the edge position. The MTI-2000 Controller precisely converts this signal to an edge position or vibration amplitude. |
