When an observer is fixating a stationary target as closely as possible, continuous involuntary rotations of the eyeball cause proportional displacements of the retinal image. In order to study the functional importance of these movements in the visual process, many methods of maintaining the image in a fixed retinal position have been reported. The limitations of each experimental technique impose restrictions on the type of problem that can be investigated. A method of producing a stabilized image is here described. It is simple, cheap to construct and yet overcomes most of the limitations of the methods referred to below.
