Fall 2009 Lecture Notes: 11. Astronomical Measurements, CCD Arrays, Array Correction 1 Check In: 10:30 — 10:35, 5 min Homework must run or 50% off per problem Questions before we start? 2 Quiz 1: 10:35 — 10:55, 20 min 3 Types of Astronomical Measurements: 10:55 — 11:05, 10 min Imaging: positions Photometry: brightnesses Spectroscopy: wavelength dependence of light Often combine 2 of these: hyperspectral imaging, spectrophotometry, imaging photometry Variation in time, often at high cadence 4 What’s After the Telescope?: 11:05 — 11:20, 15 min Telescope gathers light falling on many square meters Makes image in its focal plane (draw with focus way back to leave room for elements) Signal sorting elements Filters (show response function) Dispersers (prism, grating, grism) Reimaging optics Adaptive optics Detecting the final signal QE = quantum efficiency, fraction of photons detected
