this system only support the playback of optical pick-up heads including the recording
ones, but the system cannot record the data onto discs.
it possible to evaluate DVD-RAM?[ O-PAS800 ]
it is possible by adding optional board.
is the difference between OPU-1000 and O-PAS800?[ O-PAS800 ]
is designed for R&D of optical pick-up heads, and it has recording function.
O-PAS800 is only for playback evaluation without recording function. This low
cost system is designed for quality assurance.
many measurement does it need to complete the scheduling?[ SHOT-500 ]
scheduling needs to be repeated until the diffraction efficiency of each hologram
becomes stable. From our experience, it takes 3 times to make the diffraction
efficiency of the hologram stable, and the optimum power can be selected. However,
it depends on the characteristics of the material and the number of multiplexing.
long does it take for 100 multiplexing?[ SHOT-500 ]
takes 2 hours including recording and playback. However, the operator can
deal with other works during the measurement, because the system can measure automatically.
much is the power for one pulse?[ SHOT-1000 ]
is NA?[ SHOT-1000 ]
fast is the disc rotational speed?[ SHOT-2000 ]
90 and 300rpm.
it possible to record and playback the disc without address information?[ SHOT-2000
the system can record and play without address information with high-spec encoder
(324,000 division out of one rotation of disc <81,000ppr>).
