Investigation of Luminescent Diode Arrays for Photochromic Film Recording
Abstract
The work of this report is directed toward the optical recording of time-sequential information from a spatial array of hydrophones or other sensors. The time sequence of signals from the sensor array is initially a space-time matrix of data. An optical recording process is required which will convert this data into a two-dimensional spatial matrix. Such a recording process will require the following elements: 1. A photographic recording film or other medium 2. A writing head capable of simultaneous recording of data in parallel columns on the film from many information channels. 3. A hydrophone signal distributor to transfer the signal from each hydrophone to the matching channel of the writing head, with signal amplification or other input matching to assure compatibility with the writing head. This report will assess the practicability of such a recording system in which the recording medium is photochromic film and the writing head is an array of luminescent semiconductor diodes. The diode arrays considered here will be made by neutron transmutation doping since this technique promises high density packing of luminescent diodes with high optical power density per unit area. The recording medium to be considered will be photochromic film because it can be repeatedly re-used, and therefore offers the possibility of long term use with a relatively low volume of film. It also offers the property of high resolution storage of the information.
