这种微型照像机可能会给物联网带来启示。帕特里克·吉尔(Patrick Gill)兴奋地向我展示一幅很小很模糊的《蒙娜丽莎》,画像是黑白打印的。这幅画其实没什么可看,但却真的是蒙娜丽莎,留着长长的黑发,带着谜一般的微笑。不过,比起这张低分辨率的达·芬奇名作本身,它的诞生过程更有意思:它由一个仅宽200微米的无镜头相机拍摄。这个相机比铅笔尖还小。 Such micromirrors may provide implications for the Internet of Things. Patrick Gill excitedly showed me a very small, fuzzy “Mona Lisa,” with black and white prints. This picture is actually nothing to see, but it is really Mona Lisa, with long dark hair, with a ridiculous smile. However, its birth was even more interesting than the low-resolution Leonardo da Vinci masterpiece itself: it was shot by a cameraless lens that was only 200 microns wide. This camera is smaller than a pencil tip.
