Abstract:
We present a THz detector based on AlGaN/GaN HEMT technology implemented for a multi-pixel array and tested in a confocal THz imaging system. The multi-pixel array shows good homogeneity where the ratio between the most and the least sensitive pixels is less than two times. The detector has been tested in a confocal system at 300 GHz and the pictures show a good resolution.
