A design of a scatterometer is described for applications of Mie theory. The instrument comprises a goniometer, a lock-in amplifier, a laser, and a photomultiplier tube (PMT). An embedded control programmable hardware and Windows-based Virtual Instruments simplify the design of automation of the scatterometer. The software has been modularly designed to provide independent control of the stepper motor for the motion of goniometer arm, running and on-line displaying of angular scans, auto storage of the angular scan data. The obtained benefits include facilitation of advanced data-collection techniques and collection of higher quality data. Quasimonodisperse particle of the latex have been characterized with this set up. The measured size particles are close to the reported nominal values. This result indicated that the experimental setup warrants adequate quality measurement, which allows a reasonable solution to inverse problem.
