| 181 | METHOD AND APPARATUS FOR ANALYSIS OF A SAMPLE OF CELLS | EP06844041 | 2006-12-22 | EP1963927A4 | 2010-08-11 | GUSTAVSSON MATS; SEBESTA MIKAEL |
| A non-destructive method and device for analyzing a sample comprising transparent living and/or dead cells, by 5 means of a digital holographic microscope, where the sample (8) is exposed to light from a laser (2). The light that travels through the cells in the sample will experience a difference in the optical path length compared to the surrounding media and the wave front that emerges from the 10 cells will thus be phase shifted. This distortion can be detected in the digital hologram, which is reconstructed from the interference pattern detected by a digital sensor (17), such as a CCD or a CMOS, as phase differences or phase shifts and thereby creating a digital hologram. The 15 phase shift of each element of the hologram is then used for analyzing the characteristics of the cells in the sample. | ||||||

| Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device 1 comprises a light source 10, a first modulator 20, a second modulator 30, a lens 40, a beam splitter 41, a photodetector 46, and an arithmetic unit 50.

| This three-dimensional shape measurement method comprises: a projection step for projecting an interference fringe pattern (F) having a single spatial frequency (fi) onto an object surface; a recording step for recording the pattern (F) as a digital hologram; and a measurement step for generating a plurality of reconstructed images having different focal distances from the hologram, and deriving the distance to each point on the object surface by applying a focusing method to the pattern (F) on each of the reconstructed images. The measurement step extracts the component of the single spatial frequency (fi) corresponding to the pattern (F) from each of the reconstructed images by spatial frequency filtering, upon applying the focusing method, and makes it possible to achieve a highly accurate measurement in which the adverse effect of speckles is reduced and the advantage of a free-focus image reconstruction with holography is used effectively. | ||||||
