If we are given the focal length value and also the distance of three collinear points ($A,B,C$ with $AB= BC= 2$ cm , $AC= 4$cm) from focal plane is given and its images from the respective focal plane too ($A'B' =3$cm, $B'C'= 6$cm) . Is it possible to find the optical centre of the lens by construction ? Is it unique?
- Note: The values are not given except the distance between points. I just want a method you may assume any values
