Set Up

In this work, the implementation of Digital Holographic Microscopy for detection of microorganisms in blood is proposed. Some hemoparasites, like Filaria and Trypanosoma Cruzi, can be identified in blood samples by their movement, which is oscillatory and propagates throughout the sample. Particularly, this behavior is considered for the T. Cruzi parasite movement characterization. By comparing two consecutive holograms, a final image of the vision field in which the parasite presence becomes evident is attained. The experimental set-up design for Digital Holographic Microscopy implementation is described and a discussion about the influence of the parameters required for holographic image quality is presented. The results obtained by different numerical reconstruction methods are compared.
