An easily portable apparatus for flicker fusion experiments is described. It uses crossed polarizers to produce modulated beams and a light guide made of optical fibers to mix these beams for producing a sinusoidally modulated stimulus of which the frequency, the modulation amplitude, the luminance, the color adaptation light, and the field size can be varied independently.
