Time Dependent Recording Of Images Transmitted Over Optical Fibers

A system is being developed to record temporally and spatially resolved data after transmission through 1 km of optical fiber. Wavelength multiplexing techniques are used to transmit many spatial points over each 62 1m fiber. Light from the output end of each fiber is de-multiplexed back into a spatial line. Four lines of data are focused sequentially across the input face of an RCA streak tube. System sensitivity is increas-ed by coupling a microchannel plate image intensifier to the streak camera output. The image intensifier output is recorded on film. The streak camera gives 200 spatial points at a 25% CTF over a dynamic range of 20 db. The total usable streak length is 120 ns with a resolution of 600 ps.
