Diffractive imaging system and method for the reading and analysis of skin topology
First Claim
1. An apparatus for acquiring an image of skin topology, comprising:
- at least one light source configured to form a source beam;
at least one illumination diffractive optical element (DOE) disposed in the optical path of the source beam and configured to diffract the source beam, thereby forming an illuminating beam;
a skin-contact surface disposed in the optical path of the illuminating beam and configured to at least partially reflect the illuminating beam at regions of a boundary between the skin-contact surface and skin not in contact with the skin-contact surface, thereby forming a reflected beam;
a least one imaging diffractive optical element (DOE) disposed in the optical path of the reflected beam and configured to diffract, redirect and focus the reflected light beam, thereby forming an image beam; and
a sensor array configured to receive at least a portion of the image beam and thereby to detect an acquired image.

Abstract
An apparatus and a method for acquiring an image of skin topology. The apparatus comprises at least one light source, configured to form a source beam; at least one illuminating diffractive optical element (DOE) disposed in the optical path of the source beam, configured to diffract the source beam, thereby forming an illuminating beam; a skin contact surface, disposed in the optical path of the illuminating beam, configured to at least partially reflect the illuminating beam at regions of the boundary between the skin contact surface and skin that are not in contact with the skin contact surface, thereby forming a reflected beam; at least one imaging diffractive optical element (DOE), disposed in the optical path of the reflected beam, configured to diffract the reflected light beam, thereby forming an image beam; and a sensor array, configured to receive at least a portion of the image beam and thereby to detect the acquired image.

27. A method of acquiring an image of skin topology, comprising:
-
directing a source beam from a light source to at least one illumination diffractive optical element (DOE), thereby diffracting the source beam and forming an illuminating beam; directing the illuminating beam at a skin contact surface, configured to at least partially reflect the illuminating beam when the skin contact surface is not in contact with skin, thereby at least partially reflecting the illuminating beam and forming a reflected beam; directing the reflected beam to at least one imaging diffractive optical element (DOE), thereby diffracting, redirecting and focusing the reflected light beam and forming an image beam; and directing the image beam at a sensor array, thereby detecting the acquired image. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. An apparatus for acquiring an image of skin topology, comprising:
-
light generating means for forming a source beam; illuminating diffractive means, disposed in the optical path of the source beam, for diffracting the source beam and thereby forming an illuminating beam; skin contacting means, disposed in the optical path of the illuminating beam, for at least partially reflecting the illuminating beam at regions of a boundary between the skin contacting means and skin not in contact with the skin contacting means, thereby forming a reflected beam; at least one imaging diffractive means, disposed in the optical path of the reflected beam, for diffracting, redirecting and focusing the reflected light beam, thereby forming an image beam; and detection means for receiving at least a portion of the image beam and thereby detecting the acquire image.
