HIGH RESOLUTION MICROSCOPY BY MEANS OF STRUCTURED ILLUMINATION AT LARGE WORKING DISTANCES
First Claim
1. A method for obtaining a sub-resolution image of a specimen (52) using a microscope (100), the method comprising:
- projecting an illumination pattern of illumination light onto the specimen (52), thereby illuminating the specimen (52);
at least one of detecting at least a portion of fluorescent light emitted from the specimen (52) and detecting at least a portion of illumination light reflected from the specimen (52), thereby capturing a series of images of the specimen (52) at a plurality of different relative positions of the specimen (52) with respect to the illumination pattern projected onto the specimen (52), wherein between the capturing of at least two images of the series the relative position of the specimen (52) with respect to the illumination pattern projected onto the specimen (52) is shifted in a non-controlled manner; and
processing the captured images to extract a sub-resolution image of the specimen (52).

Abstract
A method for obtaining a sub-resolution image of a specimen using a microscope is provided. The method includes projecting an illumination pattern of illumination light onto the specimen, thereby illuminating the specimen, at least one of detecting at least a portion of fluorescent light emitted from the specimen and detecting at least a portion of illumination light reflected from the specimen, thereby capturing a series of images of the specimen at a plurality of different relative positions of the specimen with respect to the illumination pattern projected onto the specimen, wherein between the capturing of at least two images of the series the relative position of the specimen with respect to the illumination pattern projected onto the specimen is shifted in a non-controlled manner, and processing the captured images to extract a sub-resolution image of the specimen.

12. A large distance microscope (100) for fluorescence and/or reflection illumination observations of a specimen (52), the microscope (100) comprising:
-
a light source (10;
11;
12) configured to emit illumination light;a pattern generation system (20;
22;
24) arranged in the optical path of the illumination light, said pattern generation system (20;
22;
24) configured to generate an illumination pattern of the illumination light;at least one objective (40) arranged and configured to illuminate the specimen (52) by projecting the illumination pattern onto the specimen (52); and an image capturing system (70) configured to detect at least one of at least a portion of fluorescent light emitted from the specimen (52) and to detect at least a portion of illumination light reflected from the specimen (52), thereby capturing a series of images of the specimen (52) at a plurality of different relative positions of the specimen (52) with respect to the illumination pattern projected onto the specimen (52), wherein between the capturing of at least two images of the series the relative position of the specimen (52) with respect to the illumination pattern projected onto the specimen (52) is shifted in a non-controlled manner. - View Dependent Claims (13, 14, 15, 16)

17. A computer implemented method for generating sub-resolution images of a specimen (52) based on a series of images of the specimen (52) obtained by a microscope (100), wherein the series of images is obtained by projecting an illumination pattern of illumination light onto the specimen (52), thereby illuminating the specimen (52), and at least one of detecting at least a portion of fluorescent light emitted from the specimen (52) and detecting at least a portion of illumination light reflected from the specimen (52), thereby capturing a series of images at a plurality of different relative positions of the specimen (52) with respect to the illumination pattern projected onto the specimen (52), wherein between the capturing of at least two images of the series the relative position of the specimen (52) with respect to the illumination pattern projected onto the specimen (52) is shifted in a non-controlled manner, and wherein said method comprises the steps of:
-
receiving the series of images of the specimen (52); for each received image determining the non-controlled shift of the relative position of the specimen (52) with respect to the illumination pattern projected onto the specimen (52); a-posteriori shifting of each received image to reverse the corresponding non-controlled shift of the relative position of the specimen (52) with respect to the projected illumination pattern, thereby obtaining a corresponding shifted image; and processing the shifted images to extract a sub-resolution image. - View Dependent Claims (18)
