The clinical advantages of a scanning laser ophthalmoscope (SLO) and video imaging of fundus pictures are described. Image quality (contrast, depth of field) and imaging possibilities (confocal stop) are assessed. Imaging with different lasers (argon, He-Ne) and changes in imaging rendered possible by confocal alignment of the imaging optics are discussed. Hard copies from video images are still of inferior quality compared to fundus photographs. Methods of direct processing and retrieval of digitally stored SLO video fundus images are illustrated by examples. Modifications for a definitive laser scanning system - in regard to the field of view and the quality of hard copies - are proposed.
描述了扫描激光检眼镜(SLO)的临床优势以及眼底图像的视频成像。评估了图像质量(对比度、景深)和成像可能性(共焦光阑)。讨论了使用不同激光(氩激光、氦氖激光)成像以及通过成像光学系统的共焦对准实现的成像变化。与眼底照片相比,视频图像的硬拷贝质量仍然较差。通过示例说明了直接处理和检索数字存储的SLO视频眼底图像的方法。针对最终的激光扫描系统,在视野和硬拷贝质量方面提出了改进建议。
