Methods:Fifty paired embalmed cadaveric humeri (twenty-five pairs:fourteen from male donors and eleven from female donors) were scanned in medial-lateral and anterior-posterior position according to the humeral retroversion by CT. Images of the humeri in the transverse planes at the lowest border of neck,20mm and 40mm distal of LBN(LBN-20、LBN-40), isthmus, head-neck anterior-posteriorwere obtained. Sixty-one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset, head position, head-shaft angle, head to tuberosity height, head thickness, curvature radius, articular surface arc, neck diameter, isthmus position, proximal and distal border of isthmus, maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes, including LBN, LBN-20,LBN-40 and isthmus.

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。

It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.
