Abstract
A PLZT optical shutter array includes an optical shutter array, a driving circuit, a temperature compensating circuit, an IC control unit, a driving IC and a temperature sensor. Temperature of the optical shutter array is detected by the temperature sensor, and based on a voltage representing the temperature and a reference voltage for driving optical shutter element, a driving voltage for the optical shutter element is generated in the temperature compensating circuit. The driving voltage is applied to the optical shutter element through the IC control unit and a driving IC. As a result, a voltage applying apparatus for a light signal emitter which has a simple structure and allows cost reduction is provided.
