The controller uses a spectrometer to convert any light signals that it receives from the sensor. It then calculates distance values using the integrated signal processor (CPU) and transfers the data via its interfaces or the analog output.

Polychromatic white light is generated by an SLED. The light is coupled into an optical fiber.

With a sensor for distance measurement, the light of the fiber is separated by a beam splitter. Part of it radiates a firmly installed reference object. The other part radiates the measurement object. The light reflected by both the reference and measurement object is received by the sensor and conducted into the controller.

The confocal chromatic measuring principle Polychromatic white light is focused onto the target surface by a multi-lens optical system. The lenses are arranged so that the white light is dispersed into monochromatic wavelengths by controlled chromatic aberration. To each wavelength, a specific distance is assigned by factory calibration. Only the wavelength which is exactly focused on the target is used for the measurement. An optical arrangement images the light reflected onto a light sensitive sensor element, on which the corresponding spectral color is detected and evaluated. In the case of multi-peak measurements, several distance points are evaluated accordingly.

Rough and structured surfaces cause interferences within the laser point (left) which leads to a faulty projection on the sensor element. This effect becomes particularly obvious with metallic surfaces. The small laser line of the optoNCDT LL sensors compensates for this effect (right) and enables stable measurements on metallic surfaces.

Laser-line sensors for reliable measurements on metallic surfaces

The optoNCDT LL sensors operate with a small laser line. The laser line and special software algorithms compensate for disturbances caused by surface roughness, defects, indentations or minute holes on metallic surfaces. This is how optoNCDT LL sensors achieve the highest precision with measurement tasks involving metals.

Requires special sensor alignment for reflecting surfaces:
angle of incidence = angle of reflection

Specially aligned DR sensors from Micro-Epsilon provide high accuracy and signal stability on directly reflecting surfaces

Calibration certificate of all supplied sensors confirms the achieved performance

optoNCDT sensors are equipped with intelligent control features which ensure high signal stability with bright/dark transition, regardless of the color and the brightness of the measuring object. This optimally adjusts the exposure time or the amount of light for the exposure cycle just performed or the next exposure cycle. These controls enable smooth signal courses without outliers even in dynamic measurements.

Stable control regardless of color & brightness

•  Real-Time-Surface-Compensation
•  Measuring the degree of reflection during exposure and control in real-time

The Active Surface Compensation provides stable distance signal control regardless of target color or brightness.

The Advanced Surface Compensation feature operates with new algorithms and enables stable measurement results even on demanding surfaces.

The real time surface compensation feature compensates for changing reflectance properties in the current measurement cycle. Each individual laser pulse is controlled in real time depending on the surface properties of the measuring object.

The Advanced Real Time Surface Compensation with its improved dynamic range enables a more precise real time surface compensation. This ensures maximum compensation of fluctuating reflectivity while generating stable measurement values with high accuracy.

Among inductive displacement sensors, the eddy current principle occupies a unique position. Measuring via eddy current is based on the extraction of energy from an oscillating circuit. This energy is needed for the induction of eddy currents in electrically-conductive materials. Here, a coil is supplied with an alternating current, causing a magnetic field to form around the coil. If an electrically conducting object is placed in this magnetic field, eddy currents are induced which form a field according to Faraday’s induction law. This field acts against the field of the coil, which also causes a change in the impedance of the coil. The impedance can be calculated by the controller by looking at the change in the amplitude and phase position of the sensor coil.
