摘要：
We describe Cornell's near- infrared camera system PHARO (Palomar High Angular Resolution Observer) built for use with the JPL Palomar Adaptive Optics System on the 5 m Hale telescope. PHARO uses a 1024 x 1024 HgCdTe HAWAII detector for observations between 1 and 2.5 mum wavelength. An all- reflecting optical system provides diffraction- limited images at two scales, 25 and 40 mas pixel(-1), plus a pupil imaging mode. PHARO also has a coronagraphic imaging capability and a long- slit grism spectroscopy mode at resolving power approximate to 1500. The instrument has been in use with the AO system at Palomar since early 1998.
