Description
In 1816, using a pair of plane mirrors made of metal, and mounted together at a very obtuse angle, the French civil engineer Augustin Jean Fresnel (1788-1826) was able to observe the effects of optical interference. This instrument is based on that research. The form was is sometimes associated with Thomas Young, the English physician and natural philosopher who also championed the wave theory of light.
