    • The present invention is related to a compact microscope able to work in digital holography for obtaining high quality 3D images of samples, including fluorescent samples and relatively thick samples such as biological samples, said microscope comprising illumination means (1,41) at least partially spatially coherent for illuminating a sample (2) to be studied and a differential interferometer (5) for generating interfering beams from said sample (2) on the sensor (33) of an electronic imaging device (7), said interferometer (5) comprising namely tilting means (17) for tilting by a defined angle one the interfering beams (28 or 29) relatively to the other, said tilting resulting into a defined shift (27) of said interfering beam on the sensor of the electronic imaging device (7), said shift (27) being smaller than spatial coherence width of each beam, said microscope being able to be quasi totally preadjusted independently from the samples so that minimum additional adjustments are required for obtaining reliable 3D images of samples.
    • 本发明涉及能够在数字全息术中工作以获得样品的高质量3D图像的紧凑型显微镜,包括荧光样品和相对较厚的样品例如生物样品,所述显微镜包括至少部分空间上的照明装置(1,41) 用于照射要研究的样品(2)的相干性和用于在电子成像装置(7)的传感器(33)上产生来自所述样品(2)的干扰光束的差分干涉仪(5),所述干涉仪(5)包括 倾斜装置(17),用于相对于另一个倾斜定影角度的一个干涉光束(28或29),所述倾斜导致所述干涉光束在电子成像装置(7)的传感器上的限定位移(27) ),所述偏移(27)小于每个光束的空间相干宽度,所述显微镜能够独立于样品被准全部预调整,使得最小加法 为了获得样品的可靠3D图像,需要进行调整。
