A spatial telescope can be used to create a reduced image of an object as shown here where such a system of lenses is used to create a 5 times compressed image of a watch face along side an identical watch. The time-domain telescope operates in an analogous way to this spatial system but is capable of shrinking temporal optical waveforms in time by a factor of 27. (Credit: Mark Foster) |
