Based on the analysis of the luminous characteristics of typical lasers and optical properties of cylindrical lenses,a novel optical system for laser panoramic fuse,which uses two sets of cylindrical lenses with orthogonal sagittal planes to improve the scattering angle of laser beam and uses four sectors to realize the panoramic function,is proposed in this paper.

Finite element analysis of diffracting surface of sagittally focusing crystal in double-crystal monochromator;

Analysis of the focusing error of sagittally focusing double-crystal monochromator;

The principle of dynamically bending of the crystal in a sagittal focusing monochramator by flexural hinge-based bender was presented and the geometric parameters of bender and crystal were optimized.

This paper briefly introduces the sagittal focusing and monochromic principle about the beam between 5～265 KeV?Sagittal focusing monochromic principle about beam is based on Bragg law (2dsinθ=nλ),and the monochromic beam is abtained by changing Bragg angle θ.
