Research on Imaging System of Artificial Compound-Eye and Moving Object Detection

To solve the problem of moving object detecting in the wide field, this paper establishes a new artificial compound imaging system and proposes moving object detection algorithm. According to the unique principle of receiving and processing of visual information from animal compound-eye, the model of artificial imaging system consists of a micro-lens array and CCD device with planar array, capt...

Optical materials for near infrared Wollaston prisms

The optical characteristics of birefringent materials transmitting in the near IR (0.9− 2.5 μm) are analyzed. Wollaston prisms with large beam separation and virtually free from lateral chromatism – e.g. with fields of view > 1 arcmin and image elongation < 0.3′′ – could be manufactured using AgGaS2 or LiYF4 (YLF). These materials are used for non linear applications and may therefore find anot...

Nonlinear optical effects in artificial materials

We consider some nonlinear phenomena in metamaterials with negative refractive index properties. Our consideration includes a survey of previously known results as well as identification of the phenomena that are important for applications of this new field. We focus on optical behavior of thin films as well as multi-wave interactions.
