影象细部再现的能力不仅与乳剂的解象力有关,而且也与清晰度、锐度、频率一反差特性有关。Нитка等研究了乳剂层厚度和其中所含的卤化银浓度对影象清晰度(A)和频率—反差特性的影响。并指出,当卤化银在乳剂层中的表面浓度(C_(Ag)/m~2)一定时,随着层厚(h)增加,A值下降,而当它的容积浓度(C_(Ag_/cm~3)一定时,层厚增加,A值变化不大,但对卤化银浓度和频率—反差的关系未作明确的阐述。本文研究了卤化银在乳剂层中各种浓度和解象力(R)的关系。试验用的乳剂为低
The ability to reproduce details of the image is not only related to the resolution of the emulsion, but also to the sharpness, sharpness, frequency-contrast characteristics. Нитка et al. Studied the effect of the thickness of the emulsion layer and the concentration of silver halide contained therein on the image sharpness (A) and the frequency-contrast characteristic. It is pointed out that when the silver halide concentration in the emulsion layer is constant (C Ag / m 2), the value of A decreases as the layer thickness increases, cm ~ 3), the layer thickness increases and the value of A does not change much, but the relationship between silver halide concentration and frequency-contrast is not clarified.In this paper, the effects of silver halide concentration in the emulsion layer R). The test emulsion is low
