  1. For a number of historical and technical reasons, hockney envisions a camera obscura based not on a lens but on a concave mirror ( curved inward like a shaving or makeup mirror ), which can also project an image onto a screen

    由於歷史與技術上的若干理由,霍克尼推想出一種不採用透鏡、卻利用凹面鏡的暗箱(凹面鏡是一種內凹的鏡子,比如刮鬍子或化妝時用的鏡子) ,這種鏡子也可以把影像投射到屏幕上。
  2. Just as a double convex lens enlarges, so a double concave lens reduces

    正象雙凸透鏡可以放大那樣,雙凹透鏡也可以縮小。
  3. Some are flared ? that is, thicker at the rim than in the center, like a concave lens

    有些呈喇叭形即邊緣較中心厚,類似凹透鏡。
  4. We fabricated a large computer - generated holography on a concave lens surface to test the convex secondary mirrors surface

    在凹透鏡表面上製作出了用於凸非球面檢測的曲面全息圖。
  5. We demonstrate experimentally the technique to fabricate large does in the thick film on a concave lens ( mirrors ) surface with precise alignment by using the strategy of exposure twice

    採用兩次曝光的方法在凹透鏡表面上厚光刻膠中製作衍射光學元件。
  6. The interferometric zone plate is the essential of hoes, which is the interference between plane wave and sphere wave, can focus the light beam by diffraction, instead of the way which conventional lens or concave mirrors do

    摘要干涉式波帶板系由平面波和球面波兩道光波干涉而成,為研究全像光學元件的基礎,其可經由繞射作用達到聚焦效果,猶如使用傳統凸透鏡或凹面鏡所產生的效果。
