Abstract

Using the sensitive characteristic of fiber grating, the standard characteristic of the equal-intensity beam has been measured in our experiments. The data are compared with their theoretical values. The results indicate that the measurement of fiber grating is effective and exact for monitoring standard beam. The theoretical value and the experimental value coincided very well. An applied method to measure Young's modulus of material is proposed.
