Abstract

Some of the general characteristics of focal plane imaging systems and associated optics are discussed. Detailed discussion is focused on the two large millimeter-wavelength focal plane arrays presently in operation: the 8-element 1.3-mm-wavelength NRAO array on the 12-m telescope and the 15-element 3-mm-wavelength array on the FCRAO (five College Radio Astronomy Observatory) 14-m antenna. Other systems and relevant technology under construction or in the development phase are also described. >
