F(u) = ∫∞ -∞ f(x) exp(-i2πux) dx = ∫∞ -∞ exp(-x^2) exp(-i2πux) dx = exp(-π^2 u^2) : While controlled by the publisher, partial previews
where $c_n$ are the Fourier coefficients. For $f(x) = \sin(2\pi x)$, we have: Fresnel and Fraunhofer Diffraction (Chapter 4) This is
An optical system has an impulse response given by: : While controlled by the publisher
: Wave-optics analysis of coherent optical systems and the Fourier transforming properties of lenses.
Practice switching between the spatial domain (using convolutions) and the frequency domain (using transfer functions). If the problem involves large distances, the Fraunhofer approximation simplifies the solution to a direct Fourier Transform of the aperture. 2. Fresnel and Fraunhofer Diffraction (Chapter 4) This is where many students struggle with the math.
