Изобретение относитс к прибо ростроению, а именно к записи и воспроизведению информации, и может быть, использовано при записи оптической фонограммы.The invention relates to instrumentation, namely to recording and reproducing information, and can be used when recording an optical phonogram.
Известно устройство дл записи оптической фонограммы, содержащее источник света, оптическую систему, моду тор в виде зеркального, гальванометра , механическую щель и диафрагмуСО .A device for recording an optical phonogram is known, comprising a light source, an optical system, a mirror-mode modulator, a galvanometer, a mechanical slit, and an aperture CO.
Недостатком этого устройства вл етс больша инерционность из-за наличи механических элементов.The disadvantage of this device is a large inertia due to the presence of mechanical elements.
Наиболее близким по технической к предлагаемому вл етс устройство дл оптической записи фонограммы, содержащее установленные по ходу луча источника света оптйчес кую систёТТу, модул тор, дефлектор и носитель записи, генератор линейноизмен ющегос напр жени , первый . выход которого соединен с блоком управлени , дефлектором и с первыми входами двух компараторов, а второй выход через последовательно сое диненные генератор гас щих импульсов и элемент ИЛИ - с блоком управлени модул тором, а также входную шину звукового сигнала, подключенную к второму входу одного из компараторов и через фазоинвертор к второму входу другого компаратора L23The closest in technical terms to the proposed invention is a device for optical recording of a phonogram containing an optical system installed along the beam path of the light source, a modulator, a deflector and a recording medium, a linearly-varying voltage generator, the first. the output of which is connected to the control unit, the baffle and the first inputs of the two comparators, and the second output via a sequentially connected extinguishing pulse generator and the OR element to the modulator control unit, as well as an input audio bus connected to the second input of one of the comparators and through the phase inverter to the second input of another comparator L23
Недостатком известного устрой10 ства вл етс низкий динамический диапазон из-за высокого уровн шума при получающейс фонограмме согласно записи ее известным устройст вом.A disadvantage of the prior art device is the low dynamic range due to the high noise level in the resulting phonogram according to the recording of its known device.
