Abstract

In the paper the results of simulation and experimental investigation are presented of an optical frequency discriminator with an apodized, fiber Bragg grating of a constant period, cooperating with an identical grating of the sensor. Assuming the nonlinearity of the discriminator's conversion characteristic not greater than 1%, a conversion range of 0.30 nm was achieved, for gratings with a 3 dB bandwidth of 0.45 nm. Discriminators of such a type can be useful in many problems of dynamic measurements of mechanical quantities. Their certain inconvenience is the necessity of using an optical circulator, which is more expensive than a fiber optic coupler.
