More Information
Summary:The application discloses a digital holographic microscopy with a variable resolution, which comprises a lifting table, a coherent point light source, an image sensor and a control circuit, wherein the lifting table is used for mounting the coherent point light source; the coherent point light source is used for providing coherent light and irradiating an observed object; the observed object is asemi-transparent object; a light wave directly transmitting a transparent region of the observed object is reference light; a light wave diffracted by the observed object is object light; the image sensor is used for recording holographic interference stripes generated when the reference light and the object light are interfered; and the control circuit is used for controlling the lifting table and the image sensor to regulate a display resolution and obtain three-dimensional information of the observed object. According to the application, the coherent point light source is used for irradiating the semi-transparent o
