Research Abstract |
To realize real-time imaging of millimeter wave electric field distribution by using a live electro-optic imaging camera, generation method of modulated light at a wavelength of 775nm with a modulation frequency of 100 GHz is successfully developed. The modulated light is applied to the live electro-optic imaging camera and imaging of a millimeter wave electric field at 100GHz is realized. In order to improve the sensitivity of electro-optic imaging, pixels for image sensor with polarizers is designed. The extinction ratio of 42 was achieved. For efficient amplification of detected signal, a differential detection circuit is designed. Through these researches, basic technologies for highly sensitive real-time millimeter imaging have been developed.
