Abstract
Methods and apparatus for increasing the quality of digital images produced by systems using uncorrected lenses where in-focus elements in the image space of the lens are detected and recorded as directed by data in a lookup table that specifies where light from addresses in the lens specimen plane come to focus in the lens image space.
Claims17
A method of creating a digital image of a specimen at a specimen plane using an uncorrected lens, which lens has an image space which includes an image plane, and which lens focuses light from the specimen plane at different locations in the image space, including at the image plane and planes other than the image plane, comprising:
- moving a light sensor through the image space;
- and
- sensing with the light sensor light from the specimen wherever it comes to focus in the image space, including at planes other than the image plane;
- ascribing values to the sensed light;
- and
- creating a digital image of the specimen from the ascribed values, wherein the image so formed is corrected for aberrations in the uncorrected lens.
A method of creating a digital image of a specimen at a specimen plane using an uncorrected lens, which lens has an image space which includes an image plane, and which lens focuses light from the specimen at different locations in the image space, including at the image plane and planes other than the image plane, comprising:
- sensing light from the specimen where it comes to focus in the image space, including at planes other than the image plane;
- ascribing values to the sensed light;
- and
- storing the ascribed values, wherein the locations in the image space where light is sensed are specified in a lookup table wherein the lookup table stores location addresses in the specimen plane and, for each such address, stores a plurality of location addresses in the image space.
A method of creating a digital image of a specimen at a specimen plane using an uncorrected lens, which lens has an image space which includes an image plane, and which lens focuses light from the specimen plane at different locations in the image space, including at planes other than the image plane, comprising:
- moving a light sensor through the image space;
- and
- sensing with the light sensor light from the specimen where it comes to focus in the image space, including at planes other than the image plane;
- wherein said sensing step comprises directing the light sensor to different locations in the image space, as specified by data in a lookup table, wherein the light sensor has an array of data transmitting addressable sensing pixels that are selected for data transmission, and the data in the lookup table includes addresses of specific sensing pixels.
A method of creating a digital image of a specimen at a specimen plane using an uncorrected lens, which lens has an image space which includes an image plane, and which lens focuses light from the specimen at different locations in the image space, including at the image plane and planes other than the image plane, comprising:
- sensing light from the specimen where it comes to focus in the image space, including at planes other than the image plane;
- ascribing one or more values to the sensed light;
- and
- storing the ascribed values, wherein the locations in the image space where light is sensed are specified in a lookup table wherein the lookup table stores location addresses in the specimen plane and, for each such address, stores one or more location addresses in the image space.
A system for creating a digital image of a specimen at a specimen plane using an uncorrected lens, which lens has an image space which includes an image plane, and which lens focuses light from the specimen plane at different locations in the image space, including at planes other than the image plane, comprising:
- a light sensor movable in the image space and having an array of data transmitting addressable sensing pixels for sensing the light from the specimen where it comes to focus in the image space, including at planes other than the image plane;
- a data lookup table containing location addresses in the image space where said light sensor is to sense the light from the specimen;
- a sensor driver that moves said sensor to various locations in the image space;
- and
- a sensor controller that specifies for any given location specified in said lookup table which pixels transmit data.
