Abstract
Abstract A method and apparatus for optically recording dual images of the same body wherein a first image is reflected directly into a camera through a light discriminating filter, and a second image of the body is reflected into the camera through an optical path defined by an arrangement of reflective surfaces having a second light discriminating filter in the path such that the two images may be discriminated after recording.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
A dual image optical system comprising surface means for receiving light rays reflected from a body: a beam splitter in a direct line of optical alignment with said surface means and said body permitting light rays reflected from said body to pass therethrough to impinge on said surface means, a plurality of light reflectors angularly disposed relative to said direct line of optical alignment including a light reflector disposed to receive said light rays reflected from said body orthogonal to said direct line of optical alignment, first light filter means in said direct line of optical alignment between said body and said beam splitter, and second light filter means disposed in the optical path of said plurality of light reflectors between said body and said beam splitter.
Claim 2
Dependent Claim
127 words
A dual image optical system comprising surface means for receiving light rays reflected from a body: a beam splitter in a direct line of optical alignment with said surface means and said body permitting light rays reflected from said body to pass therethrough to impinge on said surface means, a plurality of light reflectors angularly disposed relative to said direct line of optical alignment including a light reflector disposed to receive said light rays reflected from said body orthogonal to said direct line of optical alignment, first light filter means in said direct line of optical alignment between said body and said beam splitter, and second light filter means disposed in the optical path of said plurality of light reflectors between said body and said beam splitter.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1 wherein said surface means includes a high speed motion picture film.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1 wherein said first light filter means transmits a portion of the light spectrum different from said second light filter means.
Claim 5
Dependent Claim
61 words
The apparatus of claim 1 further including a shutter disc between said film and said beam splitter having light filters of the same light transmitting characteristics as said first light filter means alternating with light filters of the same light transmitting characteristics as said second light filter means, whereby alternate frames of said film will record alternate views of said body.
Claim 6
Dependent Claim
27 words
The apparatus of claim 1 wherein said first and second light filter means are polarizing filters having their directions of polarization angularly disposed relative to each other.
Claim 7
Dependent Claim
13 words
The apparatus of claim 1 wherein said beam splitter is a gelatin pellicle.
Claim 8
Independent Claim
65 words
A method of optically recording dual images of orthogonal views of the same body comprising the steps of focusing a first image of a body on an image plane: superimposing a second image of an orthagonal view of the same body on said image plane, filtering the light producing said first and second images such that they may be distinguished, and recording said superimposed images.
Claim 9
Independent Claim
65 words
A method of optically recording dual images of orthogonal views of the same body comprising the steps of focusing a first image of a body on an image plane: superimposing a second image of an orthagonal view of the same body on said image plane, filtering the light producing said first and second images such that they may be distinguished, and recording said superimposed images.
Claim 10
Dependent Claim
11 words
The method of claim 7 wherein said images are simultaneously recorded.
Claim 11
Dependent Claim
11 words
The method of claim 7 wherein said images are alternately recorded.
