THz coherent optical computer
Coherent optical computer(COC) is a optical imaging system which has 2 lens for defining a spatial frequnecy plane and an imaging plane.
Due to its extream broadband nature, THz Imaing systems based on COC don't have to get full spatial frequnecy scanning.
Instead of the spatial frequnecy scanning, whole frequnecy part of T-ray can be used in imaging process.
Therefore, images are obtained from much less waveforms.
Our result shows only 30 waveforms can give well images.
