精密儀器是指用以產(chǎn)生、測量精密量的設(shè)備和裝置，.中勘測繪工程___r大理精密儀器哪家好
，包括對精密量的觀察、監(jiān)視、測定、驗證、記錄、傳輸、變換、顯示、分析處理與控制。精密儀器是儀器儀表的一個重要分支。
 精密儀器種類繁多、結(jié)構(gòu)各異。對于用于測量的精密儀器而言，云南中勘測繪工程有限公司，中勘測繪工程，可將其結(jié)構(gòu)分為基準(zhǔn)、感受轉(zhuǎn)換、轉(zhuǎn)換放大傳輸、瞄準(zhǔn)/讀數(shù)、數(shù)據(jù)處理、顯示記錄、驅(qū)動控制、機(jī)械結(jié)構(gòu)等八大功能部件。但并不是說一臺精密儀器中必須包含上述八大功能部扌件，而是應(yīng)根據(jù)儀器功能的要求有所選擇
1．機(jī)械技術(shù)
 儀器各部分的安裝固定，儀器測量精度、定位精度和運動精度的保證，由精密機(jī)械系統(tǒng)來實現(xiàn)和完成。精密儀器的測量控制對象也通常為機(jī)械結(jié)構(gòu)的運動量。
 2．電子技術(shù)
 實現(xiàn)信號的轉(zhuǎn)換、傳輸、放大。研究對象包括：
 ①測量電路：實現(xiàn)信號的轉(zhuǎn)換。
 ②計算機(jī)控制：包括信號處理分析，以及在此基礎(chǔ)上的自動控制（發(fā)出控制指令）。
 ③伺服驅(qū)動：電子與機(jī)械部分的接口，按控制指令的要求控制被控對象實現(xiàn)預(yù)定的動作。
 3．光學(xué)技術(shù)

，實現(xiàn)光學(xué)信息的處理和控制。
 光、機(jī)、電技術(shù)相結(jié)合進(jìn)一步擴(kuò)大了現(xiàn)代精密儀器的應(yīng)用領(lǐng)域。[1]
