To measure a medical object, especially a model of a tooth specimen by a simple method.
In this device for detecting a medical object, especially a model of a tooth specimen, a position detecting sensor having projection units 13-15 and light receiving units 18-21, movable in the projection direction is installed, a specified trigonometrical survey angle α is given between a projection optical path 10 of the projection units 13-15 and an observation light path 11 of the light receiving units 18-21, and the projection light path 10 is oriented in parallel to the moving direction of the position detecting sensor, and in addition, the trigonometrical survey angle α is made smaller than 10° to 5°, a light receiving array having the light receiving units 18-21 positioned in parallel and comprising plural pixels capable of individually evaluating is installed, the pixels cooperate with a signal processing device 21, and a means 19 for extending a beam in the perpendicular direction to the light receiving array is arranged within the observation light path 11.
