Design of dynamic focusing circuit for testing system of projection cathode ray tube with double beams
雙束投影管測試臺中動態聚焦電路的研製 -
Auto - e - focus system means that voltage of focus polar can be auto adjusted. and auto - optics - focus system means that the optic system composed of screen of projection tube microscope and area ccd can be auto focus
自動電聚焦指對投影管聚焦極電壓的自動調整，而自動光學聚焦系統是指對投影管發光屏?顯微鏡? ccd組成的光學系統的自動聚焦。 -
In this dissertation a new system that test crt projection tube resolution is bring forward against deficiency example slow test speed great affection because of artificial factor in the line - resolution - test system
本文針對crt投影管解析度線陣ccd測試系統測試速度慢、人為因素影響大、只能測試一維方向解析度的缺點，提出了一種新的解析度測試系統。 -
The system could rest projection tube resolution in two dimension adopting area - ccd, but also raise precision and speed of resolution - test because of realization of auto focus system that absolutely exclude the affection because of artificial factor. auto - focus system include auto - e - focus system and auto - optics - focus system
該系統不僅採用面陣ccd使該系統能夠測試投影管二維解析度，而且由於實現了自動聚焦系統使得解析度測試完全不受人為因素的影響，大大提高了解析度測試的精度和速度。
