This chapter describes the most common setups that scientists use for generating light
stimulation, from lab-made approaches to commercially available technologies. The studied
optical stimulation systems are divided into nonimage-forming and image-forming
arrangements. Two classical systems widely used are among the first: the Maxwellian view
system and the Ganzfeld stimulator. Between the image-forming arrangements, the focus is
on approaches that consider off-the-shelf devices and the recent appearance of multi …
