Abstract
This paper will discuss the development and results of a new field portable test set for Gen 2 and Gen 3 night vision goggles that automates many of the tests supported by currently available NVG test products. The major innovation is the use of MTF testing with a knife edge target. MTF testing is established in the laboratory environment and well suited to replace the operator's interpretation of the USAF 1951 resolution chart. Results will be presented to show the more consistent performance of the MTF approach as compared to the known operator variations when humans determine resolution. Other standard tests are semi-automated and/or video-assisted, such as infinity focus, spot defects, and distortion. The presentation will show repeatability across test units and operators on the key tests. The presentation will include automatically generated examples of the report files for each test run on each goggle. All of these capabilities are provided in a package that matches the form factor of other products in use to test NVG’s. A discussion of the user interface and the ease of use of the system will be included as well as the improvement in the test time for each goggle type.
