在非银盐感光材料的研究中,对于重氮感光胶片解象力的测定是一个课题。重氮感光胶片以分子成象,具有很高的解象力。但投影解象力计不能精确测定高解象力的感光材料。近来虽有介绍“解象力全息法测定计法”,但该方法由于存在技术上难以做到之点,所以也只能作近似估计解象力之用。我们认为,可以利用激光制作的全息光栅间接测定感光材料的解象力。
In the research of non-silver salt photosensitive material, the determination of the resolving power of diazo photosensitive film is a subject. Diazo film with molecular imaging, has a high resolution. However, the projection imager can not accurately measure the high resolution of photographic materials. Although recently introduced the “solution to the method of determination of holographic method”, but because of the existence of the method is difficult to technically point, it can only be used as an approximate approximation of the imagination. In our opinion, the resolution of photosensitive materials can be measured indirectly by using holographic grating fabricated by laser.
