Fiber Optic Sensor Principles
The Fotonic Sensor™ is a non-contact instrument, which uses the fiber optics lever principle to perform displacement measurement, vibration analysis and surface-condition measurements. The Fotonic Sensor transmits a beam of light through a flexible fiber-optic probe, receives light reflected from a target surface, and converts this light into an electrical signal proportional to the distance between the probe tip and the target being measured. A simplified example of the fiber optic principal is shown in Figure 2. The output signal voltage from the fiber optic sensor is then used to determine position, displacement, vibration amplitude, frequency and waveshape of a [...]

Target Material and Characteristics
Target Material and Characteristics Transparent/Opaque Targets There are a number of measurement systems that are capable of measuring a target that is opaque. When it comes to transparent targets, the measurement system being used must match the material of the target being measured. For example, if you’re attempting to measure plastic you should use a contact-type measurement system such as a micrometer. When performing a soft target measurement, such as film, a non-contact measurement system (such as a laser displacement sensor) should be utilized. Hard/Soft Targets Objects made out of hard material (such as a block of wood), would [...]
Measurement Errors
Measurement Errors At some point in the manufacturing process you’ll find that differences in measurement results (measured values) will begin to show up due to one error or another. A variety of issues can contribute to a measurement error. As a result you need to have countermeasures in place so that you’re prepared. If you encounter a measurement error, it’s vital that you examine the cause of the error very carefully before using a countermeasure. Keep this in mind if you wish to maintain the quality of your product. Types of Errors in a Measurement System Gross Errors – [...]
What is a displacement sensor?
What are Displacement Sensors (Displacement Gauges) and Dimension Measurement Systems? What is a displacement sensor? A displacement sensor (displacement gauge) is primarily used to measure the range of where an object has to travel and in relation to a reference position. Displacement sensors have multiple uses. Its primary use is for dimension measurement to figure out an object’s width, height, and thickness. Accuracy, application and usage environment is required when selecting the best equipment. What is a measurement sensor? A measurement sensor is a device that is used to measure an object to ascertain its dimensions such as by [...]
Measurement List
Measurement List Displacement sensors/measurement systems make many different types of measurements possible. Typically the application environment and the measurement target determines the type of measurement method that should be used for optimum results. There are several types of measurement systems that you should become familiar with: Dimension Measurement Thickness Width Height/Step Outer Diameter Angle Radius / Inner Diameter Displacement Measurement Run-out/Vibration Eccentricity Stroke Positioning Edge Position Gap/Clearance Profile Measurement Warpage and Flatness 2D Shape 3D Shape Thickness For those searching for Thickness Measurement Systems If you’re searching for the best method of measuring thickness, the process may not be [...]

Important Terminology for Measurement System Selection
Important Terminology for Measurement System Selection Mounting conditions / Mounting mode – to properly measure an object/target with the aid of a laser displacement sensor, you must reflect the light from the object to the receiver. Measurement systems that use a triangulation method for measurement, along with variable surface conditions of the object, have sensor heads that are installed at an angle so that light can be reflected and received in the proper manner. Opaque targets – both the sensor head and the target must be installed parallel to each other so that a portion of light hit the [...]
