一、简介测定感光材料的模量传递函数,是现代评价感光材料画面微观质量较优的方法,它可以较简便地衡量整个系统的成象质量。这次改造的测微密度计,是由德国Zeiss六十年代生产的GⅡ型测微光度计和上海风光CMT透射密度计经过改装组合而成的。
I. INTRODUCTION Determining the modulus transfer function of photosensitive materials is a modern method for evaluating the microscopic quality of photosensitive materials. It can measure the image quality of the whole system relatively easily. The modified micro-density meter, by the German Zeiss sixties produced G Ⅱ micrometresometer and Shanghai scenery CMT transmission densitometer modified combination made.
