The accuracy, reliability, speed and cost of the methods used for malaria diagnosis are key to diseases' treatment eventual eradication. However, improvement in any one these requirements can lead deterioration rest due their interdependence. We propose an optical method that provides fast detection malaria-infected red blood cells (RBCs) at a lower cost. is based on combination deconvolution, topography three-dimensional (3D) refractive index reconstruction RBCs by use transport intensity...
Multispectral microscopy enables information enhancement in the study of specimens because large spectral band used this technique. A low cost multimode multispectral microscope using a camera and set quasi-monochromatic Light Emitting Diodes (LEDs) ranging from ultraviolet to near-infrared wavelengths as illumination sources was constructed. But use provided by non-monochromatic induces variation focal plan imager due chromatic aberration which rises up diffraction effects blurs images...
Refractive index retrieval is possible using the transport intensity equation (TIE), which presents advantages over interferometric techniques. The TIE method valid only for paraxial ray assumptions. However, diffraction can nullify these model Therefore, refractive problematic reconstruction in three-dimensions (3D) a set of defocused images, as effects become prominent. We propose to recover 3D by combining and deconvolution. A brightfield (BF) microscope was then constructed apply...
Three-dimensional reconstruction in brightfield microscopy is challenging since a 2D image includes from in-focus and out-of-focus light which removes the details of specimen’s structures. To overcome this problem, many techniques exist, but these generally require an appropriate model Point Spread Function (PSF). Here, we propose new images restoration method based on application Multivariate Curve Resolution (MCR) algorithms to stack achieve 3D without need for PSF. The statistical...
