This paper presents the development and research of a compact digital holographic microscope model based on Gabor's in-line holography scheme. The model is implemented on the Raspberry Pi Zero 2W platform, ensuring portability and low system cost. The capability to record holograms of diffraction gratings and biological samples has been experimentally confirmed. A comprehensive numerical approach has been developed to analyze the system's limitations, evaluating the influence of five key factors on resolution: object-to-sensor distance, temporal and spatial coherence of the source, pixel size, and field of view.
The method was validated using the USAF-1951 test target. It has been established that the most significant limitations are associated with pixel size and the geometry of the optical setup. The proposed tool allows for optimizing microscope parameters at the design stage without conducting physical experiments.
