class="postmsg">在目前通用的理论中，要是光强变的均匀主要的有两种方法：一种是使用毛玻璃，另一种是使用导光板。首先毛玻璃制作比较粗糙（给人的感觉），使用起来似乎无法保证比较好的均光效果；导光板主要的是利用侧面导光，所以能量比较小。本人知道就上述两种方式，所以斗胆在论坛里发个原创，希望对光源均光比较熟悉的大侠们可以出来讨论下，一方面可以提升创建论坛的初衷——交流，另一方面也可以提高我的见识。所以提如下问题：1你知道的比较好的均光，还有哪些方法？2针对毛玻璃均光，还有什么细节的要求？？？大家尽情的讨论吧...</div>

嗯，这个资料介绍的挺好。顺便问下有关于毛玻璃（磨砂玻璃）的资料吗？谢谢了哦</div> <div class="postmsg">扰模，整形，应该都可以达到效果吧</div> <div class="postmsg">有很多方式的,看你怎么用.比如投影机中使用光棒可以实现匀光,使用复眼镜头也可以达到匀光。<br /> <br /> 在手电筒中，使用带有微细结构的反光碗可以达到匀光，比如反光碗是由很多小平面组成的就可以达到与复眼透镜相同的效果。</div> <div class="postmsg">积分球感觉不错 具体的可以问下我们公司技术;电话：18200571202</div> <div class="postmsg">有没有什么好办法<br /> 要简单实用的</div> <div
