Lazer ve Çizgisel Ccd Algılayıcı Tabanlı Optik Çap Ölçüm Sisteminin Geliştirilmesi
Bu çalışmada lazer ve çizgisel CCD(Charge-Coupled Device) algılayıcı tabanlı bir optik çap ölçüm sistemi geliştirilmiştir. Bu şekilde bir ölçüm sistemi ile optik temassız çap ölçümleri gerçekleştirilmiştir. Bir lazer diyot ve kollimatör lens kullanarak paralel bir ışık demeti oluşturulmuştur. Paralel ışık demeti karşısına çizgisel CCD algılayıcı yerleştirilmiş ve lazer ışık demeti ile aydınlatılmıştır. Paralel ışık demeti içerisine bir nesne konumlandırılıp çizgisel CCD algılayıcı üzerine nesne gölgesi düşürülmüştür. Bu şekilde çizgisel CCD algılayıcıda gölge altında kalan kısımlardaki pikseller aydınlanmadığından, nesnenin çapı oluşan gölgeden belirlenebilmektedir. Çalışmada silindirik kesit alanlı nesnelerin çapının temassız olarak ölçülmesi %0,24 - %1,34 hata payı ile gerçekleştirilmiştir
Development of Laser and Linear Ccd Sensor-Based Optıcal Diameter Measurement System
In this study, laser and linear CCD(Charge-Coupled Device) sensor-based optical diameter measurement system was developed. In this way, optical non-contact diameter measurements were carried out with the measurement system. A parallel light beam was created with a laser diode and collimator lens. Linear CCD sensor was placed across of the parallel light beam and illuminated by laser light beam. Parallel light beam into an object was positioned, the object shadow occurs on a linear CCD sensor and pixels of this section were not illuminated. So that the object's diameter can be determined from the shadow. In this study, cylindrical cross-sections of objects was carried out to measure of diameter as contactless. The relative errors of measurement were in the range from %0,24 - %1,34
