Día: Martes 10 de Julio de 2018
Lugar: Seminario TI-2213 (Edificio TI)
In this seminar, we present an overview of our work on our published work on using 3D optical imaging for automated disease identification.
This review includes using digital holographic microscopes for cell parameter extraction and cell classification for automated disease identification. Also, we present a compact lensless bio sensor using random phase encoding for cell identification. Experimental results and theoretical analysis will be presented. Compact 3D printed instruments will be discussed. Our approach to cell identification is based on optical sensing and imaging to capture opto biological signatures of the cells under inspection to be processed with a digital processor or hardware for cell analysis and disease identification. The sensing may include digital holography, off-axis two-beam digital holographic microscopy or on axis digital holographic microscopy. In addition, we discuss self-referencing digital holographic microscopy for field portable bio sensing systems. In a new work, we have described a lensless sensing system using pseudo random phase encoding for cell identification which can result in a low cost compact bio sensor. The self-referencing approach with digital holographic microscopy using shearing interferometry uses a common path for both the object and reference beam. This approach is very stable and robust to vibrations, and is field portable. The seminar will address the challenges and potential of these systems for healthcare in areas with limited access to advanced facilities.
