这种要求也能实现？只要懂的光路可逆这一基本光学原理就不可能提出这种无理要求！不管镀啥膜，两面的反射率和吸收可以不一样，但是透射率肯定是完全一样的，所以楼主的要求是不可能实现的。当然，存在像汽车玻璃上的那种看似两面的透射率不同的薄膜，其实这种薄膜两面的透射率也是没有差别的，差别的是反射率和吸收率，光的单向效应是两面的信噪比相差很大造成的。简直了，这么多的光学同仁在这里费劲心机的要去做一个做不出来的东西！可悲！</div>

审讯室，或者是辨认嫌疑犯的地方的玻璃，他的两面效果是一样的。<br /> 你可以这样做，晚上，你在房间内，开很亮的灯，室外如果是比较暗的话。你是看不见窗户外有没有人的。你在室外，则能把室内看得很清楚。<br /> <br /> 难道你没发现，在使用这种玻璃的时候，内外环境不一样么？<br /> <br /> 还有小汽车的门上的玻璃，当汽车观上门的时候，你从外面基本是看不清楚里面的。里面则能看清楚外面。如果。你把小汽车天窗打开，让阳光射进来，这时候，你在汽车外也能看到汽车内了。<br /> <br /> 也是说，当玻璃两面的光线环境不一样的时候，玻璃反射的光的强度，远大于透射的光的强度的时候，透射出来的信息，就被反射的信息给淹没了。反之，亦然。</div> <div
