제품 FAQ

What is a Star Target?

Siemens star charts are based on black and white areas. For resolution measurements (according to ISO 12233), the variation between black and white areas displays a sinusoidal shape.

Each star in the image provides many different frequencies, such as low frequencies at the outer radius and high frequencies at the inner radius.

How to use a Star Target?

The center of the test card is covered by a registration mark for software-based automated detection. The radius of each star modulation is examined by software. The results are combined to form a graph called the MTF curve. The same frequency is measured at 25 points in the image. This measurement is always objective.

What information can we get from MTF Curve?

The system's limiting frequency. The resolving performance of the camera from low to high frequencies. Image sharpness during image processing. Resolution can be checked in several diagonal directions, both horizontally and vertically.
