Abstract
PURPOSE: To obtain stable information recording with good accuracy, by the constitution that the optical system converting the time series signal into area change signal does not include mechanically moving parts.
CONSTITUTION: A plurality of segment shape transparent electrodes are formed in matrix shape at front and rear sides of an electro-optic element 4, and a signal performing D/A conversion of time series signal is fed to the front via lead 5 and a signal with signal processing after A/D conversion is fed to the rear side via a lead wire 6. Thus, the time series signal is converted into area chart and recorded on a photosensitive material 9 with an optical system consisting of light source 1, collimate lens 2, polarizer 3, photodetector 7, cylindrical lens 8, and after development 18 and printing 19, the power spectrum of time series signal is obtained with a monochromatic coherent light source 20, collimate lens system 21, Fourier transform lens 22, and photoelectric converter 24.
