What is the measuring principle of 3D laser scanner?
scanCONTROL 3D scanners are used for precise inline 3D measurements in numerous applications. Scans are performed by moving the scanner or the target. Due to their low weight, the scanners are ideally suited both for robotic applications and inline production monitoring. These 3D laser scanners are characterized by high dynamics, absolute precision and their compact size. With the scanCONTROL 3000 and the new scanCONTROL 3002 series, Micro-Epsilon offers a comprehensive portfolio with numerous measurement areas, Red and Blue laser technologies and extensive accessories.
The scanCONTROL 3D laser scanners are based on the latest GigE Vision and GenICam standards and can therefore be integrated into a wide range of image processing environments. The powerful 3DInspect software is available for parameter setting, evaluation and output.

3D laser scanners for inline applications
The scanCONTROL 3D scanners feature a wide range of different measurement areas from 25 x 15 mm up to 200 x 300 mm. Regardless of the size of the measurement area, these laser scanners impress with fast measurements and high precision at the same time.
The variety of measurement areas allows, on the one hand, both the acquisition of smallest details and structures, and, on the other hand, the measurement of large objects with a large offset distance. For this reason, scanCONTROL 3D scanners are used in various industries.
3D scans for integrators and end users
For the integration into the customer’s environment and image processing programs, the scanCONTROL 3D scanners offer a comprehensive SDK (Software Development Kit) based on the industry standards GigE Vision and GenICam. The unique Valid3D technology enables lossless display and processing of the 3D point clouds.
The scanCONTROL 3D scanners can be operated with the powerful 3DInspect software. Numerous tools, automation functions and interfaces enable the creation, processing and output of measured values based on real 3D point clouds.
What is the measuring principle of reflectCONTROL sensor?
reflectCONTROL is intended for shape measurements of shiny objects. This sensor displays a striped pattern which is mirrored by the surface of the measuring object into the sensor cameras. The sensor provides a 3D image of the surface which allows for the topology of the components (e.g. flatness, deflection, curvature) to be determined. reflectCONTROL is specially optimized for measurement and inspection tasks, e.g., in production lines. Moreover, the sensor has a GigE Vision interface that offers GenICamcompliant data.
The colorCONTROL MFA is used for flexible color inspections and intensity testing of LEDs, displays and colored objects. The flexible positioning of the sensors in relation to the objects, as well as their high repeatability, measuring rates and dynamics are particularly favorable. One colorCONTROL MFA monitors up to 28 test objects simultaneously.
Sensors
Operating the colorSENSOR MFA controller requires sensors that are used on the measuring point. The sensors reliably detect small light spots from 3 mm and can be individually combined depending on the measurement task. The high-quality receiver sensors with plastic fiber optics are particularly characterized by their small installation dimensions. This enables highly accurate testing at different points for individually arranged test specimens. The sensor portfolio covers a wide range of working distances and spot sizes. Other versions in different lengths and temperature ranges are available as options.

What is the measuring principle for relative color measurement testing?
The measuring system for relative color measurement testing consists of an evaluation unit, the MFA-XX controller and a MFS sensor.
The sensor is connected to the controller via an optical fiber with an integrated plastic fiber. The specimen (lighting/LED) emits electromagnetic radiation with the range of 400-700 nm (light). The light emitted from the test subject is received via an MFS sensor at a working distance of approx. 5 mm. The light is transmitted via the optical fiber of the MFS sensor to a perceptive true-color sensor (XYZ) of the MFA controller.
The three wavelength frequency ranges, i.e.
X = long wave
Y = medium wave
Z = short wave frequency ranges
from the specimen are used to determine the light emitted thereby and transformed into a selected color space. These color values are calculated according to the procedure described in DIN 5033. The transformed values (color) can be queried by the controller or continuously transmitted via the interface.
Functions
Detecting electromagnetic radiation of between 400 ... 700 nm and converting it into color values
Outputting the measurement data via RS232, RS422 or USB
colorCONTROL ACS7000 is one of the most advanced inline color measuring systems in the world. Unlike conventional technologies, this system recognizes colors not just by comparing them to reference values, but also by using the reflection spectrum to ensure unique identification. Due to its very high measurement speed, the colorCONTROL ACS7000 is suitable for applications where colors and shades have to be examined on-the-fly and to very high accuracies. Due to the extremely high measurement accuracy, the system is also applied in laboratories, e.g. in industrial Research and Development. Different sensor models are available to suit various measurement tasks.
What is colorCONTROL ACS7000 measuring principle?
The sample is illuminated with homogeneous white LED light. The diffusely reflected light in a specified angle range is fed via a collecting lens and fiber optic to a spectrometer and analyzed. The diffuse spectral reflectivity of the sample is determined from the spectra of the sample and a white reference sample. The color coordinates required by the user with the respective boundary conditions such as color space, type of light, standard observer are calculated from the so determined reflection function in accordance with the methods specified in DIN 5033.
The advantage of this spectral method as compared with the three-range method is the greater accuracy of the color measurement. Thereby, the precise determination of the color values for various observation conditions (type of light, standard observer) with simultaneous coverage of the complete color space is possible.
The colorCONTROL ACS7000 color measurement system is modularly designed. Different sensors, but not at the same time, can be coupled to the controller via a fiber optic connection. Spectrometer and light source are integrated in the controller and each is connected to the sensor via its own fiber connection. The sensor is thus completely passive.
Operating Modes
Measurement of the color values: The color values of the sample are determined
and output for a specified set of measurement conditions (color space, type of light,
standard observer)
Measurement of the spectrum: The spectral reflection function is measured and
output. - Color recognition: The color values of the sample are determined and
compared with the stored reference color values in the controller. If the measured
color is within a specifies tolerance range around one of these colors, this color is
