Paper Abstract

Parameters of MTE tests on military vehicle sights have been investigated and suitable procedures for testing with a Sira-Beck 'Erost equipment evolved. A simplified MTF testing technique operating at a single spatial frequency over all azimuths reduces the amount of test data to a convenient level for subsequent assessment purposes. The equipment to carry out this test can measure dioptre settings of fixed focus eyepieces, field curvature and astigmatism. Specifications are discussed in relation to both establishing comprehensive statements to cover a design and reduced specifications for quality control purposes.
