What is the working principle of the two-dimensional imager? With the increasing demand for measuring instruments, as long as the accuracy and size requirements are involved, the accuracy of the product and the processing of the product must be verified by the size measurement device. In this process, quality inspectors often encounter two-dimensional imagers. The two-dimensional imager, also known as an image measuring instrument, mainly measures the two-dimensional dimensions of the length and width of precision parts, and can also be used to make CAD drawings of both-product dimensions in some special fields. The marble base and column used by the secondary measuring instrument greatly improve the stability of the product and is less affected by temperature. Because it is a two-dimensional size measurement, the product to be tested is relatively small. The two-dimensional imager uses its own hardware CCD, eyepieces, objective lens data cable, and video capture card to transmit the captured image to the computer's data capture card through the data cable, and then image the image through software. On the computer monitor, the user uses the mouse to make quick measurements on the computer.

The above process is basically completed in tens of thousands of seconds, so it can be regarded as a real-time detection device, or the narrow point can be called a dynamic measurement device. If the configuration of the secondary image measuring instrument is satisfactory, the device will never produce image lag. Due to the size of the workpiece, the table can choose different strokes. The brightness of the two-dimensional imager is adjustable, and the most suitable light source brightness can be selected under various light conditions. With the increasing demand for measuring instruments, as long as the accuracy and size requirements are involved, the accuracy of the product and the processing of the product must be verified by the size measurement device. In this process, quality inspection personnel often encounter two-dimensional imagers.
