Abstract

Bir enfraruj (IR) geçici termografi sisteminde, bir IR hassas, odak düzlemi tertibine sahip bir kameradan bir dizi görüntü karesi elde edilir. Ardisik olarak elde edilen her görüntü karesi, piksellerin meydana getirdigi bir tertipten olusur ve geçen zamana karsilik gelen tahsis edilmis bir kare sayisina sahiptir. Ardisik görüntü karelerinin olusturdugu kümelerden, her piksele karsilik gelen zamana karsi sicakli (T-t) verileri elde edilir. Bir objenin kalinliginin saptanmasi ve renkli olarak isaretlenmis veya gri ölçekli olarak kodlanmis bir kalinlik haritasinin üretilmesi için her pikselden alinan normallestirilmis T-t verileri egrisinin bir hizli fourier dönüskesi'nin gerçek ve sanal bilesen kisimlarinin kullanilmasiyla, termik veri görüntü karelerinden olusan kümelerin analiz edilmesi için bir yöntem de sunulmustur.
