Welcome to Physics 123 / 253


Research at the frontier in physics and other fields often deals with signals which are buried in random noise and systematic error. This course will cover techniques of experiment design, measurement, and analysis designed to avoid systematic error and optimize signal/noise ratio. The course incorporates hands-on experience with measurement equipment. Extraction of signals from noise, optimal filters and examples of low-level detection spanning a range of subjects from laboratory physics, remote sensing and astronomy will be explored. Many examples will be from detection of radiation (UV to sub millimeter) and imaging, including inverse problems and data analysis. Using these tools students undertake laboratory projects.
