Embodiment Construction

[0061] FIG. 1 shows a device 1 with a spherical housing 2 enclosing a spherical chamber 3 and having an inner wall 4 and a sample opening 5 . A plurality of light emitting diodes (LEDs) 6 are evenly distributed on the inner wall 4 for illumination of the cavity 3 . The digital imaging device 8 is directed towards the sample opening 5 through the second opening 7 . The sample stage 9 closes the sample opening 5 . A sample 10 is placed on a sample stage 9 and supplied to the lumen 3 of the device 1 . Sample 10 can be coated with a coating film, for example. The cavity can be illuminated by activating the LED 6 via a control panel (not shown). The LEDs 6 can be activated in groups or all together. They can also be started individually if desired. If they are all activated together, the light distribution in cavity 3 is substantially uniform and diffuse light conditions are obtained. If only a group of adjacent LEDs 6 are activated, the light conditions are not diffuse but d...

Abstract

A method for imaging a sample by means of a device having a cavity with black inner walls and a sample opening, the device further comprising illumination means for illumination of the cavity and a digital imaging device directed from the cavity to the sample opening, the method comprising the following steps : - presenting a sample to the cavity via a sample opening; - illuminating the cavity; - activating the imaging device to record an image of the sample; - communicating the recorded image data to a computer programmed with image analysis software to analyze the recorded image, characterized in that the inner wall of the cavity is light absorbing and in that it is at least partly provided with light point sources distributed over at least a part of the inner wall of the cavity and a selection of the light sources, dependent on the desired light conditions, is activated.

Description

technical field [0001] The invention relates to a method of imaging a sample by means of a device comprising a cavity with an inner wall and a sample opening, the device also comprising an illumination device for illumination of the cavity and a A digital imaging device for an opening, the method comprising the steps of: [0002] providing a sample within the cavity through the sample opening; [0003] - illuminating the cavity; [0004] activating the imaging device to record an image of the sample; [0005] • Transfer of recorded image data to a data processing unit programmed with image analysis software to analyze said recorded images. [0006] The invention also relates to devices used in such methods. Background technique [0007] WO99 / 042900 discloses a method and apparatus for imaging an object disposed within an internally illuminated white walled sphere using a digital camera. The images are analyzed by a computer to generate color data. The optical axis of t...
