Abstract
By using a microwave heterodyne interferometer assisted by microwave scattering techniques, computer tomographic images of spatial distributions of plasma density can be obtained. Two 9.5 GHz Gunn diodes, whose frequencies are offset by 35 MHz, are used in a heterodyne branch. In front of the detection horn antenna, multiple diodes are lined up, which scatter the microwave power with modulation frequency of 5 kHz, and the whole spatial information in one direction can be obtained by a pair of launcher-detector systems assisted by these diodes. This system is a simple and low-cost means to get images compared with popularly known multichannel interferometer techniques; still, precise, spatial resolution in the images has been observed.
