MOL The Mission Operations Laboratory Page 12 NASA MSFC Huntsville, Alabama PACE Test Target More details: The image on the left is an overview of the Air Force Test Target that was used for the LMM test target. The image on the right is a 100 x image of the smallest subsection of the test target. This image was taken with an oil immersion objective, coupled directly to the target face. The image was taken with the camera set for Autoexpose, which yielded an exposure time of 1.61 ms. The image gives a contrast ratio of ~ 73%, which should yield a very effective method for measuring image variability due to motion or de-focus. Air Force Test Target that was used for the Light Microscopy Module (LMM) test target Test target is shown on the left. It’s image, as seen (and inverted) by the microscope, is shown on the right.
