Abstract A modified stress-strain device is used to investigate the dynamical behaviour of optomechanical properties. The optical properties and strain produced in vestan fibres by different stresses have been measured at room temperature interferometrically. It has been found that the relation between strain and birefringence is linear up to strain of 12%. For greater strain the rate of change of birefringence with strain is cut off due to breaking. An empirical formula is suggested to represent the variation of the cross-sectional area of vestan fibres with draw ratio and the constants of this formula are determined. An expression has also been suggested for the birefringence related to the strain. The strain optical coefficient is determined. Poisson's ratio, Young's modulus, elastic shear modulus and the compressibility are calculated over different strain values. Microinterferograms are given for illustration.
