Abstract
Stereoscopic device including an image directing assembly, an image differentiator and an image detector, the image directing assembly having a first light inlet for receiving a first image and a second light inlet for receiving a second image, the first light inlet being spaced apart from the second light inlet, the image differentiator differentiating between the first image and the second image, wherein the image directing assembly directs the first image to the image detector via a common path, and wherein the image directing assembly directs the second image to the image detector via the common path.
Claims95
Stereoscopic device, comprising:
- an image directing assembly, having a first light inlet for receiving a first image and a second light inlet for receiving a second image, said first light inlet being spaced apart from said second light inlet;
- an image differentiator, differentiating between said first image and said second image;
- and
- an image detector,
- wherein said image directing assembly directs said first image to said image detector via a common path, and
- wherein said image directing assembly directs said second image to said image detector via said common path.
Method for producing a stereoscopic image, the method comprising the procedures of:
- receiving images of different sides of an object, through two spaced apart apertures;
- directing said images to a common path;
- and
- differentiating between said images.
Stereoscopic device comprising:
- a first light filter admitting light at a plurality of first ranges of filter wavelengths;
- a second light filter admitting light at a plurality of second ranges of filter wavelengths;
- a sequential wavelength differentiator associated with a first set of differentiating wavelengths and a second set of differentiating wavelengths;
- an image detector, receiving images from said first light filter and said second light filter;
- and
- an optical assembly located in front of said image detector,
- wherein said first set of differentiating wavelengths is included in at least one of said first ranges of filter wavelengths and excluded from said second ranges of filter wavelengths, and
- wherein said second set of differentiating wavelengths is included in at least one of said second ranges of filter wavelengths and excluded from said first ranges of filter wavelengths.
Method for detecting a first image and a second image, the method comprising the procedures of:
- determining a plurality of first ranges of filter wavelengths for a first pupil and a plurality of second ranges of filter wavelengths for a second pupil;
- sequentially differentiating between a first set of differentiating wavelengths and a second set of differentiating wavelengths, and
- detecting said first image when said first set of differentiating wavelengths is present, and detecting said second image when said second set of differentiating wavelengths is present,
- wherein said first set of differentiating wavelengths is included in said first ranges of filter wavelengths and excluded from said second ranges of filter wavelengths, and
- wherein said second set of differentiating wavelengths is included in said second ranges of filter wavelengths and excluded from said first ranges of filter wavelengths.
Stereoscopic device, comprising:
- means for directing an image and having a first light inlet for receiving a first image and a second light inlet for receiving a second image, said first light inlet being spaced apart from said second light inlet;
- means for differentiating between said first image and said second image;
- and
- means for detecting an image,
- wherein said means for directing said image, directs said first image to said means for detecting, via a common path, and
- wherein said means for directing said image, directs said second image to said means for detecting said image, via said common path.
Stereoscopic device comprising:
- first filtering means admitting light at a plurality of first ranges of filter wavelengths;
- second filtering means admitting light at a plurality of second ranges of filter wavelengths;
- means for sequentially differentiating between wavelengths and being associated with a first set of differentiating wavelengths and a second set of differentiating wavelengths;
- image detecting means receiving images from said first filtering means and said second filtering means;
- and
- focusing means located in front of said image detecting means,
- wherein said first set of differentiating wavelengths is included in at least one of said first ranges of filter wavelengths and excluded from said second ranges of filter wavelengths, and
- wherein said second set of differentiating wavelengths is included in at least one of said second ranges of filter wavelengths and excluded from said first ranges of filter wavelengths.
Stereoscopic device, comprising:
- a first pupil receiving a first image;
- a second pupil receiving a second image;
- an image differentiator, differentiating between said first image and said second image;
- at least one image detector, detecting said first image and said second image;
- and
- an objective lens assembly, directing said first image and said second image toward said image detector.
