摘要
利用直接数字成象和程控采样扫描技术,研制成了THMUT-1型智能化多功能宽带超声检测仪。一台机器可同时完成A、B、C(多断层)、声显微镜等多种功能。工作频带为5～105MHz,对样品只需一次检测,即可将结果显示在微机终端屏幕,还可进行分析、处理。利用表面成象法,把THMUT-1所得多断层C扫描测试结果重建出三维图象。
THMUT-1 multipurpose wideband ultrasonic testing instrument has been developed,in which the directly digital imaging and programmable sample scanning are used. The operation frequency range is from 5 to 105MHz. The A ,B,C modes testing can be accomplished at the same time. The result is displayed on the screen of the computer terminal. In addition.a 3-D ultrasonic image is reconstructed and displayed by using surface re-construction algorithm.
