Image measuring instrument about the light source application of 2.5-dimensional measuring instrument

The light source application of the image measuring instrument about the 2.5-dimensional measuring instrument. 2.5-dimensional measuring instrument is also called auxiliary measuring instrument, or image measuring instrument and video measuring instrument. It is used to measure the size of products and molds. Measuring elements include position, concentricity, straightness, profile, roundness and dimensions related to the datum. It is used to measure the dimensions of two-dimensional planes and is widely used in various precision industries. Mainly used for calipers, angle rulers are difficult or impossible to measure, but they play an important role in the size and angle of parts in assembly, such as silica gel, circuit board creepage distance, electrical clearance, control panel light holes, and plastic parts. Specific size, etc. can also be used to take pictures of certain parts to analyze the causes of defects. Since the image measuring instrument is an image obtained by irradiating the part with surface light or contour light, it is necessary to acquire points for measuring the part. Not all parts are measured by the secondary element measuring instrument, which is a more accurate method. The better method is more effective, and the method of measuring the size of the part is more accurate.

It is a high-precision measuring instrument, and it is not easy to apply. First, learn from all aspects of the body, and then understand the composition and purpose of surgery. Now, let's start with the light source of the image measuring instrument. In order to give you a more intuitive understanding of the light source of the image measuring instrument, the light source of the projector is located under the slide film, and the light passes through the slide film to finally form an image. The light source of the 2.5-dimensional measuring instrument is located on the upper projection sheet, and then the light is reflected by the reflection of the projection sheet. Since the light passes through the projection sheet twice, the light density is doubled, and the image projected by the 2.5-dimensional measuring instrument has a large contrast and particularly saturated colors. The light source of the 2.5-dimensional measuring instrument is also located on the top of the projection sheet, and the light is reflected by the metal film on the projection sheet. The back of the wrinkled lens is then transmitted through the projection sheet to form an image. During the imaging process, there is both reflection and transmission, so it is called a reflection-transmission combined projector. The light source of the image measuring instrument plays an important role in the image measuring instrument system. It can even be said that it determines the function of the image measuring instrument.

Therefore, it is necessary to understand the light source of the image measuring instrument, both for the operator and for the developer.
