Real-time Visualization of W-band Millimeter Wave by Live Electro-optic Imaging
In this paper, W-band millimeter wave imaging is demonstrated by a live electric imaging (LEI) system, which has been recently developed. The LEI enables a real-time imaging of RF electric fields with 100×100 pixels and the frame rate of 30 frames/sec. LEI is based on ultra-parallel photonic heterodyning. To visualize millimeter wave electric field, a W-band photonic signal at a wavelength of 775nm as a local oscillator is generated by frequency doubling of modulated light at 1550 nm. As an example, W-band LEI observation results for electric near-fields over the end of a waveguide are presented.
