Title:
【発明の名称】自由空間の電磁放射を特徴づけるための電気光学及び磁気光学感知装置及び方法
Document Type and Number:
Japanese Patent JP3388319
Kind Code:
B2
Abstract:
Apparatus and methods for characterizing free-space electromagnetic energy, and in particular, apparatus/method suitable for real-time two-dimensional far-infrared imaging applications are presented. The sensing technique is based on a non-linear coupling between a low-frequency electric (or magnetic) field and a laser beam in an electro-optic (or magnetic-optic) crystal. In addition to a practical counter-propagating sensing technique, a co-linear approach is described which provides longer radiated field-optical beam interaction length, thereby making imaging applications practical.
