A housing which is adjustable for height and within which is placed an object to be projected onto a screen also contains a light source and a reflecting system, the light emitted by the source being reflected onto the object. The top face of the housing is pierced in order to permit the passage of the luminous flux through an optical system which is placed above the housing and cooperates with a camera for photographing the projected image of the object on the screen. Adjustable means are provided for optical coupling between the camera and the assembly consisting of optical system and housing. |
