Despite much research and a long history, the Mach bands illusion has not yet been very well-understood. Quantitative data is lacking, while qualitative data is controversial. The Hennann Grid illusion, equally old, has not yet been fully explored either. A critical and a comparative review of the experiments and the conclusions is carried out, noting common results as well as contradictory ones. New experiments and a different method of measurement are then proposed. Some preliminary experiments and their results are included in the appendix together with a review of recent knowledge about the primate retina and its functioning.viii, 165 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1990.A368Mach bandsPhysiological opticsRetina -- ResearchThesishttp://scholar.lib.vt.edu/theses/available/etd-11012008-063717/
