この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。A fiber length measuring system was constructed and totally examined. The system is consisted of a projecting apparatus and a digitizer connected with a 8-bit microcomputer. They are supported by softwares listed in this paper. Their functions are briefly summarized as follows. Fiber lengths are recorded both on a printer and on a diskette by means of tracing fiber images which projected on the digitizer. The recorded lengths in a sample lot are then processed to a mean, minimum and maximum length, variance, standard deviation, and frequency distribution of the length at 0.3 mm intervals. These statistical values, including a mean of fiber lengths, in respective samples are automatically plotted against tree ages. In addition, the frequency distribution at every annual rings are printed in a three-dimensional manner. This system was effective and accurate enough (resolution ca. 0.2mm on a sample specimen) for measuring fiber length, and was able to be constructed at a reasonable price.
