Nagel氏アノマロスコープによる色覚検査補遺

抄録

In the hope to find out a method which could depict the normal range of an anomaloscope independently from the characteristics of each instrument, a theoretical formula was obtained and a construction was made. The same method also enabled the construction of the equivalent regions of protanomaly and deuteranomaly. This result conversely proved that the anomal quotient held good independently from the choice of the instrument and light sourse. Thus the normal range and the locus of the equivalent regions of protanomaly and deuteranomaly could be depicted on the graph of the relation between the anomal qnotient (A. Q.) and the scale of the color-mixing screw. These graphs were valuable when use was made of a new anomaloscope. In addition description was made on the procedure of the test of color vision with an anomaloscope and on some required precautions.
