Population and profile display of transparent bodies in a transparent mass

Claim 2

Method of displaying population and profile data of transparent bodies contained within a transparent mass wherein said bodies are not distinguishable from said mass by the unaided eye and said bodies and said mass have different indexes of refraction comprising (a) moving a specimen of the mass containing said bodies into an optical viewing position wherein said specimen is intercepted by a columned beam of parallel light rays of a schlieren optical system whereby rays penetrating said mass continue in substantially the same columned state and rays penetrating said bodies are deviated from said columned beam of light to form an image of the profile of said bodies within said mass, (b) detecting at least a portion of said deviated rays by a television camera, and converting the image into a video signal, and (c) using said video signal as the input to a kinescope display device having amplifier means, whereby the image of said bodies is amplified with respect to size and contrast to display said population and profile data.

Claim 3

Method according to claim 1 wherein said optical viewing position includes an optical window.

Claim 4

Method according to claim 1 wherein said specimen is homogeneous and contains portions of different densities.

Claim 5

Method according to claim 1 which includes the steps of providing a passage for said specimen between two closely spaced, substantially parallel optical windows and causing said specimen to continuously move along said passage.

Claim 6

Method according to caim 4 wherein said specimen is fluid.

Claim 7

Method according to caim 4 wherein said specimen is fluid.

Claim 12

Method of displaying population and profile data of transparent bodies contained within a transparent mass wherein said bodies are not distinguishable from said mass by the unaided eye and said bodies and said mass have different indexes of refraction comprising (a) providing a passage for a specimen of the mass containing said bodies between two closely spaced, substantially parallel optical windows, (b) continuously moving said specimen through said passage wherein said specimen is intercepted by a columned beam of parallel light rays of a schlieren optical system whereby rays penetrating said mass are maintained in a columned state and rays penetrating said bodies are deviated from said columned beam of light to form an image of the profile of said bodies within said mass, (c) detecting at least a portion of said deviated rays by a television camera, and converting the image into a video signal, and (d) using said video signal as the input to a kinescope display device, whereby the image of said bodies is amplified with respect to size and contrast to display said population and profile data.

Claim 13

Method of displaying population and profile data of transparent bodies contained within a transparent mass wherein said bodies are not distinguishable from said mass by the unaided eye and said bodies and said mass have different indexes of refraction comprising (a) providing a passage for a specimen of the mass containing said bodies between two closely spaced, substantially parallel optical windows, (b) continuously moving said specimen through said passage wherein said specimen is intercepted by a columned beam of parallel light rays of a schlieren optical system whereby rays penetrating said mass are maintained in a columned state and rays penetrating said bodies are deviated from said columned beam of light to form an image of the profile of said bodies within said mass, (c) detecting at least a portion of said deviated rays by a television camera, and converting the image into a video signal, and (d) using said video signal as the input to a kinescope display device, whereby the image of said bodies is amplified with respect to size and contrast to display said population and profile data.
