站长搜索科技4月18日讯 据BBC报道美国科学家近日发明一款利用光能充电相机。新相机将传感器上的光能转化为电能,然后拍照。理论上,这种相机随时都可以拍照而且永远不会断电。

目前,相机的发明者正在改进技术并希望将其商业化。

将传感器组合起来

新相机的发明者Shree Nayar教授是哥伦比亚大学计算机成像实验室的主任,他说:“数字成像技术正不断革新,无需外接电源就可以永久拍照的相机非常有用。”

Nayar说:“当我意识到太阳能电池板和数码相机电池板采用同样的组件,也就是光电二极管处理光源时,我决定生产出一款新相机。”他和工程师一道,将相机的感光度和太阳能电池板上的光电转化设备结合。接下来,他们会把光电二极管整合起来,形成一个个传感网格,它既可以感知光的强度也能把部分光源转化为电能,这样相机便可以照相。目前传感网格的大小仅仅为30x40个像素点,只能模糊地呈现一些黑白照片。Nayar和同事们一起拍摄了一部短片展示这个相机的功能。

Nayar告诉记者下一步他们会研发一个能自己供电的固态摄像传感器,并且传感网格也更大。这样,无论去哪儿,一个相机就够了。

这种自行供电的传感器也可以节约智能手机和其他配件的电量,如果不照相,这个传感器也可以是一个小型发电机。(胡骁腾)
