藝術史學者會注意後面墻上那面醒目的凸面鏡，對它捕捉了視覺世界的象徵意義加以熱烈討論，而我則會專注於它的光學特性，如焦距與聚光能力。1, cut over a head : bring up to combine the applied technique most and early for the toshiba, and is also current usage to is the most extensive. he adopts a laser head, and prepare the different slice of 2 focal distances the sony for cut over, passing the conversion differently focusing the coming respectively reading dvd with cd, its shape looking with double head to resemble respectively, because can see two sets focuse the, laser head to interiorly can t see. he reads the signal quantity is higher, but because of want the conversioning to focuse the, therefore the cost belong to the inside and so forth of level, and recognize the dish speed slow, same the implicit mechanical trouble rate is high
1切換雙鏡頭：為toshiba最早提出並應用的技術，也是目前使用最廣泛的。他採用一個激光頭，分別準備2個焦距不同的鏡片切換，通過轉換不同的聚焦鏡來分別讀取dvd和cd ，它的外形看起來與雙頭的sony相似，因為只能看到二組聚焦鏡，激光頭在內部看不見。他讀取信號質量較高，但由於要轉換聚焦鏡，所以成本屬于中等水平，認盤速度較慢，同樣隱含的機械故障率比較高。If the screen is so far away from the eyepiece that the camera can be placed between.
如果投影屏距目鏡很遠，照相機可放在兩者之間。The paper has introduced a new means on the automatic focus that take advantage of the video peak to change the position of the focusing lens to achieve a clear picture
