Multi-part mirror for focusing diffuse light

In the present study a multi-part mirror is developed for focusing only a scattered light effectively. The multipart mirror is composed from several elliptic mirrors. Several elliptic mirrors are installed on the surface of the multi-part mirror. Primary focal points of all elliptic mirrors lie on t...
