Customers set out to support the layout, connection and integration of modern hardware to build an application to study in the field of laser spectroscopy. On the basis of the customer's equipment available, INO measure Co.., Ltd. design a software system to control spectrometry of alkali metal atoms by laser spectroscopy techniques marked polarity. The equipment and diagram of system are described as diagrams and pictures below:

The requirements design of software that the customer set: In the measurement process, the computer simultaneously record signals from cathode lamps Holow, Fabry-Perot interferometers and photomultiplier tube (through 3 of Boxcar above). The data are recorded in the "steps" of the electric motor control laser wavelength. The wavelength scanning laser source controled by computer also to control simultaneously with the signal received from the Boxcar.
