Imaging in Astronomy (JHU intersession Jan 2014, Jan 2016)

About the course: This was an undergraduate level course on the basic physics of imaging and some of the practical implementation for astronomy. We started with the mathematical framework, deriving the diffraction limit both from ray-tracing and Fourier methods. We then went across the electromagnetic spectrum considering the different noise properties and technologies associated with different energy scales.

Textbook: Measuring the Universe (Rieke) with help from Fundamentals of Optics (Hecht), (McLean), and of course The Fourier Transform and its Applications (Bracewell).

I learned a lot teaching this course twice. I also attending a workshop on active learning shortly after teaching the 2nd time. I’ve compiled some thoughts about how I’d like to use active learning components in future courses in my blog post: Learning About “Active Learning.”

Fourier Optics Guest Lecture on Non-Redundant Masking and Kernel Phase (March 2015)

A lesson on the basic formalism of kernel phase interferometry, starting from a three-hole pupil mask, generalizing to an arbitrary pupil.
