本文介绍一种用于水下声成像系统中的彩色图像终端。它可以实时处理数据率为375KB/S以上的成像信号,能对C—Mode和B—Mode两种工作方式产生的图像信号进行内插处理;在B—Mode工作时能快速实时地进行座标变换,通过彩色编码器能将灰度信息转成伪彩色显示;画面上能同时显示各种成像参数和标尺数据。图像终端采用光栅扫描体制,图像存贮器的容量达512~KBIT,字符和参数值及同步控制信号由TP—805微机给出。
This article describes a color image terminal for use in underwater acoustic imaging systems. It can process the imaging signal with the data rate of 375KB / S in real time, and can interpolate the image signals produced by the two working modes of C-Mode and B-Mode. In B-Mode, it can coordinate quickly and in real time Transform, through the color encoder can gray information into false color display; screen can simultaneously display a variety of imaging parameters and scale data. Image terminal using raster scanning system, the image memory capacity up to 512 ~ KBIT, character and parameter values and synchronization control signal given by the TP-805 microcomputer.
