Visualizing Light over an Apple-ish looking Tomato w a Trillion Frames Per Sec Camera
Video of a fruit illuminated by a femtosecond laser pulse and captured at an effective trillion frames per second. Light moves less than 1 mm per frame. We have built an imaging solution that allows us to visualize propagation of light at an effective rate of one trillion frames per second. Direct recording of light at such a frame rate with sufficient brightness is nearly impossible. We use an indirect 'stroboscopic' method that combines millions of repeated measurements by careful scanning in time and viewpoints. The device has been developed by the MIT Media Lab's Camera Culture group in collaboration with Bawendi Lab in the Department of Chemistry at MIT. A laser pulse that lasts less than one trillionth of a second is used as a flash and the light returning from the scene is collected by a camera at a rate equivalent to roughly 1 trillion frames per second. However, due to very short exposure times (roughly one trillionth of a second) and a narrow field of view of the camera, the video is captured over several minutes by repeated and periodic sampling.

Okay. Watched the entire clip. A couple of things ...
1) How does this help us develop time travel? 2) Did they use government grant money for this? FAX |

I'm watching on an Apple monitor. Does that help?

I think it would have been cooler if they had used a dancing tomato.

I don't get it. Is this what happens when you open the door to a dark room that contains a tomato?

Is my mind becoming shallow, or am I right to be disappointed that some internet meme didn't jump out of the tomato?

Being a scientist is the best job ever.
All you do is write grant requests and then spend the money on wacky stuff and experiment things. Like, for example, you could receive grant money to do a study on the effects of fresh, hot, homemade pie on the reproductive cycles of nubile women. In fact, now that I think about it ... I'll see you guys in a few months. FAX |
