Multi-sensor measurement technology
The use of multiple sensors for measurement and detection has become a trend that seems to be accelerating. In today's measurements, commonly used sensors include: contact (trigger) probes, probes with color or proximity effects at the tip of the tip, camera video systems, and various types of laser probes.

A computed tomography (CT) sensor can perform deep inspection of the workpiece. Although each sensor has its specific purpose, it is becoming easier to integrate them.
Stephen Flynn, president of Optical Measurement Products (OGP), believes that the integration of multiple sensors is a trend that is not too new, although the company has added some new changes to this technology. Flynn said, "We developed our first multi-sensor system in 1986. In fact, we were at the leading edge of this technology. Now, on any of our measurement systems, we use multi-sensors. It’s no surprise.†OGP specializes in high-precision measurement systems based on video sensors. Developing a multi-sensor measurement system means integrating additional white-shirts and sensors.
Flynn believes that the development of multi-sensor measurement technology is the ability of users to measure small topography features quickly, accurately and conveniently (with only one setup). Each sensor has its own strengths and limitations – integrating them together allows each sensor to take full advantage of its capabilities. For example, OGP's high-magnification video sensors can be used to directly detect the edges of workpieces; contact probes can be used to measure the various surfaces that intersect to form an edge; laser probes and white-light scanning probes are ideal for measuring surface contours. Flynn pointed out that the increasing processing speed of low-cost computer platforms and easy-to-use measurement software are key enabling technologies for multi-sensor battery.
OGP's SmartScope series of multi-sensor CMMs are available in a wide range of sizes, from small bench-top measuring machines to floor-standing measuring machines with a wide measuring range. The latest model in this series is the sturdy large-scale benchtop measuring machine, the SmartScope Quest 300. The machine's mechanical structure is designed for multi-sensor measurements. Several optional sensors are available on the measuring machine. Workpieces with important features on different surfaces can be mounted on an MTR rotary indexing table and maneuvered to the optimum position for measurement by any available sensor.
Werth is another company that has moved from a single optical measurement technology to a multi-sensor measurement technology. Many of the new measuring machines developed include a number of rotating shafts to meet the requirements of a variety of sensing probes, including an optical probe, a laser probe, a contact probe and a high-precision tactile feel of the instrument itself. Fiber optic probe. The Werth ScopeCheck V is a classic example of these new multi-sensor measuring machines. The machinist is used to measure turning and milling workpieces in a shop floor environment. The sensors available include Werth's video probes, optical probes with full image processing, laser probes, and Renishaw's point-to-point triggering Probes, dynamic scanning probes, and Werth fiber and profile probes.
The Optiv series of measuring machines is a multi-sensor measuring system from the Hexagon Measurement Group's Brown & Sharpe (Figure 1). The Optiv measurement system uses a video camera probe as the main sensor, and the optional optional sensor includes a contact probe, a laser probe or a white light probe (WLS). The Optiv Classic measurement system launched in September 2008 is the existing Optiv Referonce, Optiv Advantage and Optiv
Entry-level model of the Performance series of measuring machines. All three existing measurement systems are designed in a modular configuration so that different sensor and measuring machine functions can be configured to provide flexibility for future measurement applications. The Optiv measurement system has more than 25 sizes and measurement accuracy combinations, as well as a variety of measurement accessories for users to choose from.
