According to the characteristic of ieee 1394 with wide bandwidth, common and real - time, the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite. before engineering realization, carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface. we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4. 5m to 100m ), compared with analog videos, have no geometric distortion, and have better luminance, contrast, definition
作為工程實現前的實驗研究，對三類具有ieee1394介面的數字錄像機和攝像機進行了視頻圖像傳輸實驗，發現無壓縮格式的按ieee1394標準傳輸的數字視頻圖像（傳輸距離從4 . 5米到100米之間） ，較原始模擬視頻圖像在幾何位置信息上沒有衰變，而在亮度、對比度、邊緣清晰度這些方面有明顯的優勢；但是按dvcam壓縮格式（常見于sony公司的系列產品，是5 ： 1的dct幀內壓縮）壓縮的數字視頻圖像，較原始模擬參照圖像有明顯的幾何畸變。 -
The result of the test, examination and probation shows that this new technology an enhance the homing precision and reduce the weight of gyroscope system by one fifth and the viewfinder maintains sound optics quality under bad conditions - no crack of glass and no distortion of metal base
檢測、試驗與試用表明，通過該工藝製造的提升鏡，使制導陀螺系統重量減少五分之一，極大地提高了制導精度，且大面積反光鏡在惡劣環境下光學質量完好，玻璃無破裂，金屬底座不變形。
