Is $I(\lambda)=I(\tilde{\nu})$ true in general in Fourier Optics?
Say the spectrum of a light bulb is given by $$I(\lambda)=I_0exp\left(-\frac{(\lambda-\lambda_0)^2}{2(\delta \lambda)^2}\right)$$
(i.e. a gaussian)
if I want the intensity in terms of the wavenumber $ …

Infinite sum of transmitted parallel light fields
I'm currently studying
optics and came across the possibility of retrieving the original electric (light field) from a pair of partially reflecting mirrors, but I am confused by several inconsistencies …

Imaging aberration
Qs: Doesn't a curved side lens produce less aberration than a flat lens in general because the overall angle of deviation is smaller in the curved lens?
Consider the following experimental results fo …

Mathematical expression for refraction within a spherical lens
Qs: How do I show that for a point object, for a ray at a large angle from the optical axis, spherical aberration (SA) produces a distorted focal length $f_{SA}$ that is shorter than the normal focal …

Misconception with Fourier Transforms in a Gaussian Light source?
So for a Michaelson Interferometer , we know that the (complex) interferogram ($I=I(\Delta)$, $\Delta$=path difference between two mirrors) is related to the intensity profile of the light source $(I_ …

Can the variation of count rate over distance for a disk radioactive source be treated as an...
So I did an experiment in which the count rate of a disk source of Sr-90 is measured using a plane detector, varied from ~0.7cm to 100cm, multiplying the count rate by the distances squared (i.e. $\fr …
