A computerized intensity detection system has been designed
and constructed using single board TK-85 microprocessor system.
Two types of hardware architectures, Address Mapped and Memory
Mapped Input-Output systems are utilized as Input module from
light detector and Output module to X-Y recorder, respectively.
A performance test on the computer system has shown that the
system hardware and software function properly with consistent
gain -of l.36O. An educational grating- used for the overall
performance test has also indicated instrumental accuracy
consistent with design limitation. A preliminary application of
this system in light scattering experiment has exhebited
qualitative features in the angular distribution of the
scattered light intensity which are consistent with theoritical
prediction.
