Applications Notes
See how Philtec fiber optic sensors solve measurement challenges in aerospace, energy, cryogenics, medical technology, vacuum systems, high-pressure environments, and advanced research applications.
25_Reflectance Compensation
The PHILTEC Reflectance Compensated (RC) fiberoptic sensor uses a ratiometric calculation of two detector signals to measure distance independently of target reflectivity. This makes the sensor output blind to surface reflectance variations.

26_RC Sensors Illustrated
Visual guide to reflectance compensated sensor operation with examples including bearing/rotor dynamics, in-process dimensional control, part-to-part measurements, and Z-axis distance with X/Y travel. Explains when RC sensors are required over D-type sensors.
30_Measurements in Fluids
Explains how submersion in fluids collimates light rays and extends sensor operating range by approximately 30%. Includes refractive index table, calibration requirements per medium, and Philtec experience with cryogenic rocket engine fluids (LH2, LOX, methane).
24_Reflectance Dependent
D-type sensors provide an output proportional to the distance and reflectance of the target. The output function is double-valued: Near-Side operation provides the highest resolution, while Far-Side operation offers moderate sensitivity with a larger operating range.
85_FO Sensor Systems
Philtec offers four versatile sensor system configurations to suit diverse operational requirements. These include the One-Part System, where the fiberoptic cable is permanently attached to the amplifier; the Two-Part System, which incorporates a cable- or bulkhead-mounted connector; and the Three-Part Vacuum Passthru or Extension Cable systems, which utilize either a dedicated vacuum flange or dual in-line connectors for specialized installation needs.
V6N9_ValveDynamics
Measurements of valve and actuator dynamics require very small sensors with wide bandwidth. Philtec fi beroptics are perfectly suited for these applications.
