那么這些問題如何解決呢？我們先來了解一下振鏡掃描的工作原理振：振鏡式掃描系統(tǒng)采用高速往復伺服電動機帶動X與Y兩片微小反射鏡片協(xié)調偏轉反射激光束來達到光斑在整個平面上掃描的目的。其不同于一般的機械式掃描系統(tǒng)：采用絲桿的傳動帶動掃描頭在二維平面上來回運動完成掃描，由于是機械式的，所以掃描系統(tǒng)的慣性大，掃描響應速度慢。
振鏡掃描時面臨的典型問題：
枕型失真
當掃描鏡在工作面上掃描一個矩形時，它得到的實際軌跡是并非一個標準矩形，而是如圖所示枕形
雙振鏡掃描會引起單軸的枕型誤差，誤差是由映射到平面時不是一一對應的線性關系，是一種原理性誤差。
解決方案
由于產生的畸變在X和Y兩個方向上不是一致的，所以不能采用常規(guī)透鏡的辦法來矯正的，可以通過畸變公式軟件的方法來修正合理的描述理想圖和畸變圖之間的地址映射關系的平面坐標變換方法能很好地解決這個問題。
