Abstract
A method comprising determining a quantitative dispersion image of an object based on a set of quantitative phase images, each quantitative phase image of the set of quantitative phase images having been obtained with a respective different illumination light wavelength.
Claims24
A method comprising:
- determining a quantitative dispersion image of an object based on a set of quantitative phase images, each quantitative phase image of the set of quantitative phase images having been obtained with a respective different illumination light wavelength,
- wherein the set of quantitative phase images comprises three quantitative phase images, wherein each of the three phase images having been obtained with one of three different illumination light wavelengths which are ordered as, wherein λshort is the shortest wavelength of the three different wavelengths, λmiddle is the middle wavelength of the three different wavelengths and Δlong is the longest wavelength of the three different wavelengths.
An electronic device comprising circuitry configured to:
- determine a quantitative dispersion image of an object based on a set of quantitative phase images, each quantitative phase image of the set of quantitative phase images having been obtained with at least three different illumination light wavelengths which are ordered as, wherein λshort is the shortest wavelength of the three different wavelengths, λmiddle is the middle wavelength of the three different wavelengths and λlong is the longest wavelength of the three different wavelengths.
A digital in-line hologram microscope scanner comprising:
- an image sensor configured to acquire, for each illumination light wavelength of a set of different illumination light wavelengths, respective two or more phase-shifted holograms of an object, wherein the distance between the object and the image sensor is fixed;
- and
- circuitry configured to;
- determine a set of quantitative phase images from the acquired phase-shifted holograms;
- and
- calculate, for each of different illumination light wavelengths and for each pixel of the quantitative dispersion image, an optical path difference based on a phase delay value of a respective pixel of the respective quantitative phase image.
