The limitations of this scheme became quite apparent with the introduction of detectors such as the plumbicon, image orthicon and vidicon.

这个方法的局限性在引进诸如氧化铅光导管摄像管，超正析象和光导摄像管之类的探测器之后变得很明显。

In this paper, we describe the conception of orthicon, orthogonal function set and completion of orthogonal function set conception and compared to them.

本文首先阐述了正交、正交函数集以及完备正交函数集的概念，并进行了深入的探讨。
