COHSI (PhD Thesis, 1998)<\/p>\n

I was part of the early stages of OH Suppression, using optics to “suppress” specific wavelengths of emission from the Earth’s atmosphere to lower the sky background to enable much deeper astronomy. I helped build the Cambridge OH Suppression Instrument over 1994-1998.<\/p>\n

OH suppression in ground-based astronomy remains an on-going area of research. Advances in new types of suppression via fibers, gratings, and \u00a0novel photonics applications are being tried on the biggest ground-based telescopes to get that “extra edge” in sensitivity.<\/p>\n

My thesis project involved the design, construction and commissioning of a near infrared night sky suppressing spectrograph called COHSI<\/a>. This instrument concept has since been evolved to a new instrument for Gemini North, called CIRPASS<\/a>.<\/p>\n
