[0019] The present invention is oriented to a large field of view super-resolution dynamic phase lensless microscopic imaging device, which consists of a partially coherent or coherent light source 1, a first parallel plate 2, a second parallel plate 3, a sample stage 4, and an imaging sensor 5. The light source 1 is used as the illumination light source of the lensless microscope, which is directly arranged above the sample stage 4, and the light emission center of the light source is located on the optical axis of the entire imaging system.
[0020] The distance H between the partially coherent or coherent light source 1 and the upper surface of the sample 4 is generally 20-40 mm, and the distance d between the camera 5 and the sample 4 is 5 μm-2 mm. The first parallel plate 2 and the second parallel plate 3 are composed of two pieces of glass, which are placed between the partially coherent or coherent light source 1 and the sample stage 4.
