Abstract
Two-dimensional optical data is transferred at a variable rate through an tical delay module formed by spatial light modulators of the ferroelectric liquid crystal type interconnected in series for data transmission by a beam splitter through which laser radiation is introduced. Operation of the light modulators is controllably interrelated to control the variable delayed transfer rate of the module.
Claims14
In a data processing system having a data source and a signal processing device through which optical information derived from the data source is processed at a predetermined transfer rate;
- data transfer means operatively connected between the data source and the signal processing device for delayed transfer of the optical information from the data source and control means connected to said data transfer means for controllably varying said delayed transfer of the optical information to the signal processing means to substantially match the predetermined transfer rate.
In a data processing system having a data source and a signal processing device through which optical information derived from the data source is processed, a source of laser radiation and data transfer means for delaying transfer of the optical information to the signal processing device at a variable transfer rate including:
- a pair of spatial light modulators respectively connected to said data source and the signal processing device and a beam splitter optically coupling the spatial light modulators to each other under control of said laser radiation.
In a data processing system having a data source, a signal processing device and optical ring means for transfer of optical information between the data source and the signal processing device, said optical ring means including optical delay means for varying said transfer of the optical information, shutter means for cylically controlling said transfer of the optical information and means for optically processing the optical information during said transfer thereof.
