Abstract
In this paper, we propose a photo response model of the optical piezo-electro actuator, which reacts by light beam. Based on response experiments by U.V. beam, the response in this model is constituted with three effects: 1) photostrictive effect; 2) pyroelectro effect; 3) thermal deformation. Those effects are different in response magnitude and response time each other; influenced by the characteristics of the light beam. In consequence, it is possible that a photo response is controlled by changing characteristics of light beam. As a whole, results of the simulations of this model agree with those of the experiments.
