Paper Abstract

A new optical expander is developed in this paper. It converts a beam of light from an Ar+ laser which has a diameter of 0.8 mm to a rectangular collimated light beam which has a height of 50~150mm and width of 1~10mm. This collimated light beam can be shifted 0~100 mm and convert 90° continually. The system is used in measuring fluid motion distribution. Its luminous energy utilization radio can reach 90%, much higher than 12.5% ratio of traditional expanding method.
