Abstract

PURPOSE:To provide the higly efficient apparatus with a simple construction by utilizing a displacement accompanied by the expantion and contraction of a photoresponsive material when a light signal transmitted through a fiber is irradiated into the material. CONSTITUTION:A signal to be measured is transmitted from one end of fibers 11 and 12 on pulse width signals S1 and S2 of light. This light signals S1 and S2 are irradiated into a belloweses 21 and 22 from the other end of fibers 11 and 12 and light energy is absorbed into photoresponsive materials 31 and 32 which are expanded heated thereby stretching the belloweses 21 and 22. The degree of stretch of the bellows corresponds to the light energy (duty ratio) of the light pulse signal irradiated and a differential lever 4 displaces according to the difference between the duty ratios t1/T and t2/T of the light signals S1 and S2. The displacement of the differential lever 4 drives a pointer 6 thrugh a link mechanism 5 enabling the magnitude of the signal transmitted to be indicated from the shifted position of the pointer.
