Abstract
A measurement instrument and method: produce light having a linear shape; direct the light toward an eye via a first lens located one focal length from the light source; provide returned light, having the linear shape, from the eye to a split-prism; split the returned light into first and second linear segments; image the first and second linear segments onto an image sensor; determine a first lateral offset between the first and second linear segments on the image sensor at a first time; determine a second lateral offset between the first and second linear segments on the image sensor at a second time; determine a difference between the first and second lateral offsets; and determine a distance that the eye moved relative to the first lens between the first time and the second time based on the difference between the first and second lateral offsets.
