Abstract: PURPOSE:To simplify the time axis expansion, compression and time delay for an electric signal, by the photoelectric conversion for a light obtained from the modulation to the light with the electric signal given to an acoustooptic processing section. CONSTITUTION:A sinusoidal signal in frequency f1 inputted to a terminal 6 is converted into an ultrasonic signal 11 by an ultrasonic wave oscillator 1 and propagates in a cell toward an ultrasonic wave absorbing member 2. When a plane wave 9 is made incident so as to cross the ultrasonic wave signal, a diffracted light in frequency f1 is obtained. The sinusoidal wave signal in frequency f1 is applied to a terminal 6' through pulse amplitude modulation. A frequency difrracted light corresponding to the sum and the difference of the ultrasonic wave signal 11 and an ultrasonic wave signal from an ultrasonic wave oscillator 1' in the light intensity appears at locations where they are overlapped spatially toward the optical axis. The signal 11 is scanned by another ultrasonic wave signal in accordance with relative speed and its sign of the two ultrasonic wave signals.  The change in the amount of output light results in the expansion of the time axis of electric signal.

Title: System for improving distortion rate of light emitting diode
Inventor: OOTA KOUICHI
IPC: H04B10/00
Filed: 1981-02-26
Abstract: PURPOSE:To improve the distortion rate with small amount of feedback, by providing  an optical frequency divider which selects a specified wavelength in a feedback type,  light emitting diode driving circuit comprising the light emitting diode, a light receiving element, and a driving amplifier, transducing the light into an electric signal, and feeding back the signal to the amplifier. CONSTITUTION:The electric signal is inputted in an input terminal 1. The difference between the signal and the feedback signal is formed in a synthesizer 2, sent to the driving amplifier 3, and amplified. Then the light emitting diode 4 is actuated and the generated output light is irradiated to the outside through an optical fiber 6. The receiving element 6 is arranged in the vicinity of the diode 4. Part of the light output from  the diode 4 is fed back to the synthesizer 2 through a feedback circuit 7. At this time,  the optical frequency divider 8 is inserted between the diode 4 and the light receiving element 6. Said optical frequency divider 8 is constituted by a reflecting plate wherein  a plurality of grooves are provided in parallel on a flat plate with an equal interval being provided. The selectivity characteristic of the divider 8 is made steep by utilizing  the fact that the angle dispersion of the reflected light is different in accordance with the wavelengths. Thus the feedback is made as small as 1, and the nonlinear distortion is compensated.
