Assessing the binocular advantage in aided vision.

Advances in microsensors, microprocessors, and microdisplays are creating new opportunities for improving vision in degraded environments through the use of head-mounted displays. Initially, the cutting-edge technology used in these new displays will be expensive. Inevitably, the cost of providing the additional sensor and processing required to support binocularity brings the value of binocularity into question.

Luminous efficiency and the measurement of daytime displays, signals, and visors.

Purpose: Measurements concerning the usability or safety of optical equipment are based on assumptions regarding luminous efficiency. The current luminous efficiency functions are derived from human sensitivity experiments taken at low light levels compared with the outdoor daytime environment. The amount of error induced by extrapolating from low light level data to high light level applications is not known.

Ocular laser exposure incident reporting.

Background: Advances in laser technology are providing opportunities for new laser applications. Once the nearly exclusive province of scientists and the military, lasers are finding increasingly widespread applications in modern life. Along with this increase in applications, it is reasonable to expect a concomitant increase in the number of accidents and occasions of purposeful misuse, resulting in excessive ocular exposures to laser radiation.
