Abstract:

The purpose of the report is to evaluate the usefulness of various laboratory tests to measure night-seeing ability of ground troops and to choose a test suitable for selection of ground troops for night operations. It is desired to choose from available test methods one which will select men with reasonable accuracy for night-seeing ability for ground night operations. One basis for selection is to test men with the available instruments and to compare these results with the ability to perform visual tasks in the field, the tasks to be of the type normally required of ground troops during night operations. Such a method was employed after preliminary tests indicated that it was possible to devise a field test which could be properly scored and which involved visual tasks of the types normally encountered by ground troops. The instruments and tests compared were AAF Night Vision Tester, Luckiesh-Moss Variable Contrast Charts, S.A.M. Tester, Luminous Plaque and the A.M.R.L. Field Test. Description of test and test equipment and results are given. Author
