Description
Известны фотоэлектрические приборы дл измерени площади кож и тому подобных материалов, снабженные компенсационным фотоэлементом , включенным противотактно основному фотоэлементу прибора и освещаемым вспомогательным источником света, перед которым установлена диафрагма с поводком, перемещающимс по щкале, градуированной в единицах площади.Photovoltaic devices for measuring skin area and similar materials are known. They are equipped with a compensating photocell, which is turned on counter to the main photo cell of the device and is illuminated by an auxiliary light source, in front of which is installed a diaphragm with a lead moving along the scale graduated in area units.
Предлагаемый прибор отличаетс тем, что в нем применена диафрагма перед вспомогательным источником света и поводок, перемещаемый по щкале, градуированной в единицах площади. Применение диафрагмы перед вспомогательным источником света позвол ет производить отсчет величины площади измер емых кож.The proposed device is characterized in that it uses a diaphragm in front of an auxiliary light source and a leash moved along a scale graduated in units of area. The use of a diaphragm in front of an auxiliary light source allows the area of the measured skin to be measured.
На чертеже схематически изображен общий вид прибора.The drawing schematically shows a general view of the device.
На пути осветител / с объективом 2 расположены два матовых стекла 3 и 4, между которыми помещена измер ема кожа или иные материалы 5. Световой поток, проход через не затемненные материалом 5 участки молочного стекла, а затем через диафрагму 6 и светофильтр 7, попадают на основной фотоэлемент 8, возбужда в последнем фототоки . Противотактно основному фотоэлементу 8 включен компенсационный фотоэлемент, освещаемый от вспомогательного источника света 10, перед которым, с целью отсчета величины площади измер емой кожи в момент компенсации, установлена диафрагма // с поводком 12. Поводок 12 перемещаетс по шкале 13, отградуированной в единицах площади по образцам-эталонам. Светофильтр 14 предназначен дл см гчени светового потока. Параллельно фотоэлементам 8 9 включен стрелочный гальванометр 15, служащий дл контрол при уравнивании фото-токов , возбуждаемых в фотоэлементах. Защитные кожухи/5 п/7 креп тс на специальной станине, в зависимости от условий производства.On the path of the illuminator / lens 2 there are two opaque glass 3 and 4, between which the measured skin or other materials 5 are placed. The light flux, the passage through the dark glass areas not darkened by the material 5, and then through the diaphragm 6 and the light filter 7, fall on main photocell 8, excites in the last photocurrent. Counterbalanced to the main photocell 8, a compensation photocell is switched on, illuminated from an auxiliary light source 10, in front of which, for the purpose of counting the area of skin measured at the time of compensation, an aperture // is installed with a leash 12. The leash 12 moves on a scale 13, graduated in units reference samples. The light filter 14 is designed to soften the light flux. Parallel to the photocells 8 9, an analog galvanometer 15 is used, which serves to control the equalization of photocurrent excited in photoelectric cells. Protective housings / 5 p / 7 are fixed on a special bed, depending on the production conditions.
