Revolutionary measurement method

Furthermore, is insensitive to ambient light. No matter how light conditions may be, the system will always deliver accurate measuring results. As the system allows for measurements without prior spraying, the infrared scanner opens completely new application areas in manufacturing. As an example, it is possible to use the system in-line for measuring objects in step with the production cycle. Moreover, the R3Dscan is suitable for all applications in which neat cleaning of the measuring object cannot be guaranteed after spraying. The complete system has a weight of around 25kg and works with a 220V power supply. One shot covers a measuring volume of 250x250x100mm³. Larger scans can be realised by relocating the scanner or the object to be measured. Furthermore, thanks to the modular configuration of the system, it is possible to connect several projectors to one single computer. Thus, no matter how large the measuring object may be, it only takes one shot to acquire the whole part. The result “OK” vs “not OK” is computed within seconds.

Omnetics uses a nickel/gold plated one-piece beryllium copper flex pin design, operable at temperatures between –55ºC and +125ºC. Wired connectors include 26 AWG Teflon ® insulated copper wire that provides up to 3 amps per line on micro sizes, and 30 and 32 AWG wiring for nano-sized connectors. A wide range of wire count and cables can be designed into custom back-shells. Cable systems include braided shields to reduce electrical noise interference (EMI) and crosstalk.

3D digitising systems based on the principle of fringe projection play an important role in industrial metrology. However, conventional fringe projection systems meet their limits when it comes to scanning reflective or transparent surfaces. In these cases the measuring object can only be digitised by preparing the surface, ie with a spray. To overcome this problem, the German company AiMESS has developed a fringe projection system that makes surface preparation unnecessary. In contrast to other fringe projection systems, the R3Dscan does not analyse an object’s reflection. Instead, it makes use of an infrared detector for tracing the energy that is absorbed by the measurement object and converted into heat. As the nature of the surface finish does not affect this patented infrared measurement method, the R3Dscan allows for instant scanning of reflective, dark or transparent surfaces. Not only spraying is avoided when applying the R3Dscan: the time-consuming procedure of placing markers on the measurement object is not necessary either. Thanks to a highly precise way of positioning, the single views of a measuring object are automatically matched to a complete data set. New latching connectors New latching Micro-D™ and BiLobe ® connectors from Omnetics Connector Corporation use a squeeze-latch system to make quick cable connections to mating connectors and panel equipment. The small, lightweight connectors are available at both 25 and 50 one-thousands of an inch spacing, and have passed extensive shock and vibration testing including pull testing exceeding 100lb pull force. The connectors are designed to be used in rugged applications such as unmanned vehicles, optical surveillance, and flight deck test equipment, where quick connect and disconnect methods are not readily available in a rectangular connection system, and in medical devices, such as surgery tools, ultrasound monitors,
