<p>PROBLEM TO BE SOLVED: To provide an ultra high-speed dimension transformer and an ultra high-speed dimension transformation and transmission device which transforms two-dimensional information into one-dimensional time information at high speed and transmit it by using an ultrashort light pulse. SOLUTION: The ultra high-speed dimension transformer comprises an illumination means 1 consisting of an ultrashort light pulse light source 10 and an optical system to shape the ultrashort light pulse, a two-dimensional spectrogram generating means 2 consisting of a dispersive element 20, a first and second Fourier transformation lenses and a first filter, a two-dimensional information display means 3 consisting of a first spatial light modulator 30, a two-dimensional information write means 4 consisting of a light source for write, a second spatial light modulator and a multiple imaging optical system, a time information generating means 5 which consists of a third and fourth Fourier transformation lenses and a second filter and converts the two-dimensional spectrogram passing through the first spatial light modulator into the one-dimensional time information, and a transmission means to transmit the one-dimensional time information. The two-dimensional information display means divides the two-dimensional information displayed on a second spatial light modulator 42 into block units, and writes them in the first spatial light modulator.</p> |
