 精密儀器是指用以產(chǎn)生、測(cè)量精密量的設(shè)備和裝置，.中勘測(cè)繪工程___r大理精密儀器哪家好
，包括對(duì)精密量的觀察、監(jiān)視、測(cè)定、驗(yàn)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(gè)重要分支。
 精密儀器種類繁多、結(jié)構(gòu)各異。對(duì)于用于測(cè)量的精密儀器而言，云南中勘測(cè)繪工程有限公司，中勘測(cè)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(dòng)控制、機(jī)械結(jié)構(gòu)等八大功能部件。但并不是說(shuō)一臺(tái)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(cè)量精度、定位精度和運(yùn)動(dòng)精度的保證，由精密機(jī)械系統(tǒng)來(lái)實(shí)現(xiàn)和完成。精密儀器的測(cè)量控制對(duì)象也通常為機(jī)械結(jié)構(gòu)的運(yùn)動(dòng)量。
 2．電子技術(shù)
 實(shí)現(xiàn)信號(hào)的轉(zhuǎn)換、傳輸、放大。研究對(duì)象包括：
 ①測(cè)量電路：實(shí)現(xiàn)信號(hào)的轉(zhuǎn)換。
 ②計(jì)算機(jī)控制：包括信號(hào)處理分析，以及在此基礎(chǔ)上的自動(dòng)控制（發(fā)出控制指令）。
 ③伺服驅(qū)動(dòng)：電子與機(jī)械部分的接口，按控制指令的要求控制被控對(duì)象實(shí)現(xiàn)預(yù)定的動(dòng)作。
 3．光學(xué)技術(shù)
 利用各種光學(xué)原理，實(shí)現(xiàn)對(duì)被測(cè)量的轉(zhuǎn)換、放大、投影、顯示、傳輸?shù)?。傳統(tǒng)的光學(xué)系統(tǒng)是與機(jī)械技術(shù)相結(jié)合實(shí)現(xiàn)其功能的，現(xiàn)代的光學(xué)系統(tǒng)又結(jié)合了電子技術(shù)，.中勘測(cè)繪工程___r大理精密儀器哪家好
，實(shí)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]
