InSARTrac is an innovative method for 3D displacement monitoring that combines terrestrial interferometric synthetic aperture radar (InSAR) and computer vision-based feature tracking. The measurements obtained are considered far superior to 1D or 2D data facilitate evaluations concerning the mechanisms controlling kinematics. This study presents results of at Mölltal Glacier in Carinthia, Austr...

Presumptive (or 'spot') tests have served forensic scientists, law enforcement, and legal practitioners for over a hundred years. Yet, the intended design of such tests, enabling quick identification drugs...

PURPOSE To evaluate the effects of three increasing powers of monovision contact lenses on both objective and subjective vision in emmetropic presbyopic patients. METHODS A prospective single-center study was conducted on 50 emmetropic presbyopic patients with a mean age of 55.4 +/- 4.3 years (range, 50 to 66). Each patient wore for 1 week a +0.75 D, +1.50 D, and +2.50 D contact lens in the n...

Five thousand one hundred and twenty-nine Wisconsin children, ages 4–12 years, were tested for colorvision deficiencies using a newly devised, precisely calibrated paper-and-pencil test. The disposable 1-page test consisted of 1 demonstration and 8 test panels. Thousands of copies of the test were produced, and they were distributed and administered in classrooms by teachers. Children wrote dir...

PURPOSE To establish reliable vision measures allowing functional monitoring in patients with severe vision loss. METHODS Legally blind and normally sighted subjects were enrolled in a repeated-measures study to determine the reproducibility of psychophysical vision measures under scotopic conditions. The tests included dark adaptometry, dark-adapted, full-field flash testing, and dark-adapte...

Various tests are in common use for determining the visual acuity (VA) in children, and this paper reports the results of an investigation into some of them in regard to their accuracy, acceptability, and comparability. Early assessment of the VA is desirable in order to detect any abnormality, but through lack of co-operation and comprehension, it cannot usually be carried out until the age of...
