Abstract: An optical encoder assembly and a method for measuring a rotation angle in which optical beams are spread over the circumference of a rotating optical disk by means of optical guides (OG). In the preferred embodiment the rotating optical disk has a pair of concentrically arranged circular patterns with alternating transparent and opaque sections. Each beam is input via optical fibers to one of a pair of concentrically disposed OGs with a cylindrical shape (COGs) respectively and propagated through the optical disk to be reflected by a mirror with two concentrically disposed circular patterns of reflective and non reflective sections, reentering the COG through the optical disk in a reverse direction. The COGs then guide the light beams back to an electronic interface that converts the optical signals into electronic signals producing position information.

Abstract: Methods and systems for performing an eye test and for detecting eye disease. A test pattern is presented to an individual. The individual fixates an eye on a fixation target. The test pattern is then hidden and a second test pattern is displayed at a different location. The individual then compares the perceived second test pattern with a pre-defined reference pattern. These steps are repeated several times, while varying the location of presentation of the patterns. Alternatively, the individual fixates on a presented fixation target. A test pattern is presented to the patient and then disappears. The individual compares the perceived pattern, with a pre-defined reference pattern. These steps are repeated while changing the location of presentation of the test pattern. It may then be determined whether the individual has an eye disease based on the comparisons.
