Abstract
Novel use is made of multiple 20 and 65 μm optic fibers coupled to LEDs to provide light stimuli in specific spatial configurations to a visual nervous system. The LEDs' currents, hence output light intensities, are modulated in a Gaussian white-noise fashion to utilize techniques, developed by Wiener, for computing nonlinear generalizations of the impulse response function for the visual system. In particular, nonlinear spatial crosstalk between adjacent regions of a crustacean eye are examined using so-called Wiener kernels. The optical and computational techniques are useful for a wide variety of research areas and are easily extended to them.
