  1. The paper lays a strong emphasis on discussing the realization of the autocontrol of raster scanning of the scanner in x - y dimension, the " tapping " of the cantilever of the tappingmode afm by a direct digital synthesizer. then a method of parallel communication between dsp and pc in epp mode is given. finally, the author discussed the digital pid closed loop control of the scanner in z - direction, the automatic approaching of the tip using step - motor, and also some electro - magnetic interferences

    論文首先簡單介紹了鏡的發展、分類、工作原理及應;接著對ti公司的tms320vc5402dsp的特點及外圍擴展作了簡單介紹;然後分章節重點講述了利vc5402dsp實現鏡的核心部件? ?壓電陶瓷管的x向和y向的光柵制;藉助直接數字集成器( dds )實現輕敲式原子力顯鏡的懸臂的「輕敲」 ; vc5402dsp的主機介面( hpi )與pc機在增強并行口( epp )模式下的通信;論文最後還介紹了管z向的數字pid閉環制,步進電機的自動進,並對實際出現的一些電磁干擾問題作了討論。
  2. In this paper, a high integrated and intelligent digital dsp - spm system is developed based on the nspm6800 spm manufactured by the beijing zhongke mechanical & electrical equipment co. at present, the pc of spm system is burdened with not only sending and receiving data, but also disposing of image, which hinders the enhancement of speed of the system. in addition, as the function of spm is expanding, including tappingmode afm, efm, mfm, scm, etc, one hand, it amplifies the range of the application of spm, on the other hand it also means that the task of autocontrol and data transfer heavier. the advantages offered by the dsp compared to analog systems include considerable flexibility in the choice of the signal processing algorithm and greater ease in managing control parameters by the host computer, which are very important for the improvement of spm

    本課題以北京市中科機電設備公司的nspm - 6800型鏡為基礎,重新設計了以dsp為制核心的制系統,主要解決原系統存在的以下問題: ( 1 ) pc機既要實時制數據的採集與發送,又要進行圖像的后處理,整個系統的實時性難以達到要求; ( 2 )隨著spm功能的擴展,一方面包括輕敲式原子力顯鏡、電場力、磁場力、容場顯鏡等技術在內的spm技術擴展了儀器的測試范圍和功能,另一方面也意味著自動制量的增加和數據處理量的增加; ( 3 ) 16位a d 、 d a都採的是購買的板卡,也通過isa槽插在pc機內,成本高,不利於擴展; ( 4 )另外,數字板通過isa槽插在pc機內,易受于擾,而且給安裝帶來不便。
