Acne conglobata (AC), perifolliculitis capitis abscedens et suffodiens (PCAS) and hidradenitis suppurativa (HS) are uncommon refractory chronic, inflammatory, scarring diseases but cause serious damage to the quality of life. These three diseases are associated with follicular occlusion. Several studies indicated topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT) improved follicular occlusion besides acne treatment. So we attempted to apply ALA-PDT to medicine resistant AC, PCAS and HS. Topical ALA-PDT was applied to 10 patients with AC, seven patients with PCAS and three patients with HS for more than three sessions. All the patients completed the dermatology life quality index (DLQI) questionnaire and were assessed for the efficacy at the baseline and on two weeks after each treatment. Adverse effects were recorded at each visit. The results showed 25.5% (5/20, two cases of AC and three cases of PCAS) of patients achieved excellent improvement after three sessions of PDT and another 60.0% (12/20, eight cases of AC and four cases of PCAS) of patients achieved good improvement. 15.0% (3/20, three cases of HS) got poor response (

为了降低分数傅里叶全息图制作的复杂性,根据信号的分数傅里叶变换的定义式和菲涅耳衍射公式,通过求解它们的点扩展函数(PSF),推导出分数傅里叶变换与菲涅耳衍射公式的等价关系,从而把分数傅里叶变换转化为菲涅耳衍射。采用人眼分辨率极限尺寸和数字微镜器件(DMD)像素的尺寸分别对物体所在平面和全息图所在平面进行抽样,运用分块算法生成分数傅里叶全息图,使计算复杂度降低为O[N2lb(N2/M2)],提出了一种可行的动态全息显示方法,最后通过DMD全息显示系统对该算法生成的全息图进行实验验证。
在以工业机器人为主体的轨道车体打磨和喷涂系统中,由于轨道车辆表面纹理特征较少和曲率变化,使得物体表面关键特征定位困难和稳定性差等问题。为解决上述问题,首先对常见的视觉传感器的优缺点进行分析,然后选择使用单目视觉技术来对车体表面特征定位方法进行研究,提出并实现了融合多传感器的方法来实现大型物体表面关键特征的定位。该方法结合使用单目相机和激光位移传感器,在算法层面上借鉴了逆映射和最近点迭代的算法。最后
