Abstract
A millimeter-wave imaging antenna array has been demonstrated for the first time at 245GHz. The array is a line of evaporated silver bow-tie antennas on a fused-quartz substrate with bismuth-microbolometer detectors. The measured optical transfer function shows that the system is diffraction-limited. If the microbolometers can be replaced by more sensitive diode detectors, the array should find application in radiometry and radar.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
