Introduction

The ability to record each microfilm system of alphanumeric characters or details of closely spaced lines and the like are different. This standard specifies a given Microfilm cameras, photographic materials and processing technology composition measurement capability of copying images detail microfilm system, which can be applied to define and control of image quality.

Since the microfilm system capable of operating in a state close to the limit of readability, the resolving power tests provide security measures to prevent information loss Shi, but other factors also affect the overall quality microfilm images.

This standard describes the ISO test chart No. 2 Resolving power Resolving power measurement method, and Figure 1 and Figure 2 shows the test patterns and Test pattern arrangement.

1 Scope

This standard specifies the microform by measuring the size of the smallest details can be identified to determine the resolving power of the method. This standard gives a test chart Sample No. 2 and ISO resolving power test chart, and gives expression resolving power of the method.

ISO resolving power test chart No. 2 for use as part of the test target, like other standards related to microfilming technology required that.

This standard applies to determine the cameras, film and processing technology consisting of microfilming systems and resolving power produced by such systems Microform achieved resolving power. In the latter case, it is not suitable for determining the reader, a reader-printer or computer output microform Resolving power (COM) imaging system.
