The development of ophthalmological sonographic equipment started as early as 1958 with the ultrasonic "slit lamp" of Baum and Greenwood. This was an immersion-type device with a closed membrane. Subsequent developments took place mainly after the introduction of the contact B-scanner by Bronson and Turner approximately 10 years ago. The instrument designed by them still serves as a source of inspiration for the creation of many "small-part" scanners. Among the special display modes featured in ophthalmological equipment, we have the deflection-modulated B-image (AB-mode) and the so-called "continuous-vector" mode for the A-trace selection from a real time B-mode image. Other examples are the specially designed A-mode equipment for measurement of the axial length of the human eye, and the A-mode equipment with a more or less standardized-gain characteristic curve of the overall amplification.
眼科超声设备的发展早在1958年就随着鲍姆和格林伍德的超声“裂隙灯”开始了。这是一种带有封闭膜的浸入式设备。随后的发展主要发生在大约10年前布朗森和特纳引入接触式B扫描仪之后。他们设计的仪器仍然是许多“小部件”扫描仪创造的灵感来源。在眼科设备的特殊显示模式中，有偏转调制B图像（AB模式）以及从实时B模式图像中选择A扫描线的所谓“连续向量”模式。其他例子包括专门设计用于测量人眼眼轴长度的A模式设备，以及具有或多或少标准化总放大增益特性曲线的A模式设备。
