My Question is as follows.
What is the effect of refractive index of an object for imaging (Photographs by high speed camera) on its size and shape information incurred from image?
Lets say ,
I keep the camera focal length, aperture, distance between camera & object, light intensity of the background constant. Put two objects of same diameter 'd' with different refractive index n1 and n2 in front of the camera one at a time. Size incurred from image of those object is of diameter d1 & d2.
My question is will d1 & d2 be the same ? or it will differ? if it differs how can I co-relate analytically/ theoretically or by ray tracing projection?
