8mm Variable-Density Sound Recording Using a Silicon Carbide Light-Emitting Diode
The electroluminescent diode provides a new means to optically record sound at very low power and in close quarters. It presents a challenge of its own to record in a variable-density system with a source of unusual characteristics. The application of this work to 8mm color film is described along with the results obtained using the diode in its original and in a modified form. The results of a simple expression for predicting the frequency behavior are also given.
