comed by those who wish to study the living
human body, because of the simplicity, high
accuracy, real time advantage, and low

ABSTRACT: An instrument capable of taking contour moiré imageries
of a living body from two opposing directions is presented in this
paper. The construction, procedures of alignment and calibration,
and the performance of the instrument are described.
RÉsuMÉ: On décrit un appareil avec lequel on peut prendre des images
moiré des corps humains de deux directions opposées. La construc-
tion et la performance de cet appareil, ainsi que les procédés d'align-
ment et d'étalonnage sont discutés.
ZUSAMMENFASSUNG: Ein Gerät wird vorgestellt, mit dem Moiré-Bilder
eines menschlichen Korpers von zwei Seiten aus hergestellt werden
kónnen. Die Konstruktion und Leistung des Gerátes sowie die Au-
fnahmeanordnung und Kalibrierung werden beschrieben.

PRINCIPLE
Let us review the principle of the
technique using a simple but accurate ap-
proach. Suppose an object is illuminated with
a point light source through a plane grating
and the object is observed through the grat-
ing. The small areas on the object which are
