"ABSTRACTWe propose a method for measuring the angular velocity of a rotating diffuser by speckle photography employing a simple optical system and single exposure. The information is extracted by pointwise and Fourier filtering techniques. A speckle pattern occurs when a ground glass for transmission and aluminum for reflection as a diffuse object is illuminated by coherent light and recorded on a negative film. To measure the angular velocity during the exposure, as the diffuser rotates the speckle pattern also rotates and each speckle elongates. Each elongated speckle becomes a rectangular slit, which produces a diffraction pattern that gives information about the object. In this experiment angular velocity at 1.36 deg/sec, 2.3 deg/sec, 2.72 deg/sec, 3.3 deg/sec and 4.3 deg/sec has been measured."

"[Penerapan fotografi hitam dan putih saat ini, sudah berbeda dengan adanya fotografi digital yang menggunakan berbagai macam warna pada foto. Perkembangan teknologi fotografi digital dalam faktor warna, optik dan resolusi memungkinkan foto mendekati gambaran realitas. Bagaimana halnya dengan fotografi hitam dan putih saat ini? Pada skripsi ini akan dibahas lebih dalam mengenai teknologi digital fotografi hitam dan putih dan penerapannya dalam fotografi arsitektur.

, At this time, the implementation of black and white photography is different in the presence of digital photography that using different colors on the photo. The development of digital photography technology in term of color, optics and resolution allows photograph become the picture of reality. What about the black and white photography at the moment? In this thesis will be discussed more in the digital technology of photography in black and white and the application in architectural photography.
