根据信息论在照相科学中的应用,可以把照相过程看作为传递信息的过程,而感光材料就是一种检测信息和记录信息的介质。近年,随着感光材料在科学摄影方面的广泛应用,人们对感光材料的检测能力愈来愈关心。在60年代初,Marchant和Millikan将检测量子效率(DOE)和信噪比(SNR)的概念应 According to the application of information theory in photographic science, the photographic process can be regarded as the process of transmitting information, and the photographic material is a medium for detecting and recording information. In recent years, with the wide use of photosensitive materials in scientific photography, people are increasingly concerned about the ability to detect photosensitive materials. In the early 1960s, Marchant and Millikan will examine the concept of quantum efficiency (DOE) and signal-to-noise ratio (SNR)
