Abstract Equipment for recording and subsequently reproducing relief or stereoscopic images. A chamber is provided with a rectangular window in the front wall and a convergent optical system facing the window. The convergent optical system directs light rays coming from an object at infinity towards the sensitive surface of a film with convex or concave lenticular elements. The plane of the rectangular window is located substantially in the object focal plane of the optical system. A dark slide shutter curtain closes off the rectangular window. The sensitive surface of the film is placed in a removable frame for receiving at least one optical surface having cylindrical lenticular elements. The chamber is suitable for both recording and reproducing relief images.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
In a device for recording relief images of remote objects, the combination of: a housing having an opening in one wall thereof; a convergent optical system disposed within said housing and aligned with said opening, said optical system being spaced from said opening by an amount substantially equal to the principal focus of such optical system, and said optical system comprising a concave mirror facing said opening and a semitransparent mirror disposed between said concave mirror and said opening and inclined at a 45* angle; a sensitive film disposed in said housing and lenticular means comprising at least one optical element overlying said film and having a surface composed of cylindrical lenticular elements, and sensitive film and overlying optical element being positioned to receive an image from said optical system.
Claim 2
Dependent Claim
130 words
In a device for recording relief images of remote objects, the combination of: a housing having an opening in one wall thereof; a convergent optical system disposed within said housing and aligned with said opening, said optical system being spaced from said opening by an amount substantially equal to the principal focus of such optical system, and said optical system comprising a concave mirror facing said opening and a semitransparent mirror disposed between said concave mirror and said opening and inclined at a 45* angle; a sensitive film disposed in said housing and lenticular means comprising at least one optical element overlying said film and having a surface composed of cylindrical lenticular elements, and sensitive film and overlying optical element being positioned to receive an image from said optical system.
Claim 3
Dependent Claim
32 words
In a device as defined in claim 1 wherein the angle subtended by the center to center spacings of said lenticular elements at said concave mirror is not greater than 3/10,000 radians.
Claim 4
Dependent Claim
45 words
The device according to claim 1 wherein said lenticular means comprises a plurality of superposed lenticular elements to form images on said film such that a correct stereoscopic image is produced thereby when viewed through said opening with a single lenticular element overlying said film.
