Abstract
Digital holography is practical technique for researching of 3D-objects parameters. There are various limitations of reconstructed image quality: speckle noise, twin image, zero order, shot noise, camera’s fixed pattern noise (FPN). In this work comparison of effect of digital camera’s main noise components on hologram reconstruction is investigated. Characteristics of different type’s cameras were used. It was obtained that for majority of cameras shot noise has higher effect on reconstructed images. However for various conditions FPN alone result in worse reconstruction quality than shot noise does. Borders of equal effect of shot noise and FPN on reconstructed images were obtained.
