Abstract: Marking apparatus for marking tissue imaged through an imaging device including a viewing element in the form of a spacer having an imaging window which provides an imaging zone through which tissue can be imaged by an imaging probe. The apparatus can include a marker implement connected to a coupling device. In some embodiments, the coupling device is configurable to position the marker implement in a first position substantially out of the imaging window and a second position in the imaging zone of the imaging window. The marker implement can apply a mark when in the second position and thereby to tissue in the imaging zone while the apparatus remains in the imaging position on the tissue. The spacer can be length adjustable in order to change the depth of focus of the imaging probe, thereby to focus at different depths within a patient's skin.

Abstract: An apparatus for acquiring a two-dimensional image of an external surface of a three-dimensional object is described. The apparatus includes a conveyor for supporting and displacing the object, a camera for capturing images of portions of the object surface, and a friction member for rotating the object. The camera is configured to capture images corresponding to successive exposed portions of the object surface, and to sequentially capture the images as respective single frames. The apparatus further includes an electronic control unit adapted to read out a sub-frame from the single frame, store the sub-frame, and assemble successive sub-frames into an assembled frame corresponding to a two-dimensional image of a surface area of the object.

Abstract: A puff tonometer includes two light sources located at diametrically opposite points, preferably equidistant from the optical axis of the objective lens assembly of the tonometer. The sources are arranged to direct light forwardly of the tonometer such that, in use, and when positioned close to a patient's eye under test, light from the two sources, after reflection by the anterior corneal surface of the eye under test, will be imaged by the objective lens assembly of the tonometer, to appear as two small areas of light in the field of view.

Abstract: A puff tonometer in which the eyepiece and objective lens form a simple telescope which is capable of presenting to the user an in-focus image of distant objects, as well as an image of light reflected by an eye under test at close quarters when viewed through the eyepiece. A Pechan-Schmidt prism inverts the image and presents to the user an image of the patient's eye which is correctly oriented and handed in a vertical and horizontal sense. The focal length of the eyepiece typically lies in the range 62-100 mm, preferably 80 mm.

Abstract: A puff tonometer which includes an object at a point in the optical path of light from a source of light in the tonometer, typically near to the source, such that an in-focus image of the object will be formed in the user's field of view when the tonometer is at the critical distance from an eye under test at which the automatic air pulse generating means will be triggered by light reflected from the eye forming an in focus image of a mask on a plurality of photoelectric sensors. A second object may be located in the same region of the tonometer as the first object, but in a plane which is spaced from the plane containing the first object, whereby its image will come into focus in the field of view just before the image of the first object comes into focus, as the unit is moved slowly towards the patient's eye.

Abstract: An output scanner for recording an image on a radiation sensitive medium comprises an at least part cylindrical support which carries the medium in use, the medium facing radially inwardly. A scanning unit is positioned radially inwardly of the support and has a generator for generating a plurality of modulated radiation beams, the beams being modulated with respective image information, and a reflector for reflecting the two beams onto the medium at respective, different positions. Optics focus the beams onto the medium. Motors cause relative rotation and traverse movement between the scanning unit and the support about and along the axis of the support respectively.
