Photonic Heterodyne Pixel for Imaging Arrays at Microwave and MM-Wave Frequencies
Figure 12
Results from the scanning of the object shown in Figure 10 with the array using an optoelectronic mixer for heterodyne detection with remote LO and IF distribution. (a): power difference measured for each pixel with and without the cross (in dB). (b): −10 dB contour for the results shown on (a).
