Research OverviewProfessor Tanguay's research interests and experience include the crystal growth and characterization of optical and optoelectronic materials; dielectric and optical thin film physics; thin film deposition technology and characterization; device processing by ion beam milling and etching techniques; electronic/photonic packaging including multichip module integration by flip-chip bonding; physical optics; the physics and technology of electrooptic, optoelectronic, and integrated optical devices (including spatial light modulators, photorefractive volume holographic optical elements, diffractive optical elements, and advanced integrated optical signal processors); photonic implementations of neural networks; smart cameras (including adaptive nonlinear dynamic range compression and color constancy); surgically-implantable intraocular cameras and multielectrode arrays for retinal prostheses; immersive panoramic cameras; 3-D visualization and full-volume 3-D displays; chaos in neural networks; 2-D and 3-D conformal multielectrode neural probes and neural unit array prostheses for the brain; hybrid biological/electronic/photonic computational modules; and the fundamental and technological limitations of optical information processing and computing.
Professor Tanguay's current research programs are highly interdisciplinary in nature, and include the development of hybrid electronic/photonic multichip modules for vision applications; the design, fabrication, and testing of an intraocular camera to be used in conjunction with advanced conformal multielectrode arrays to form a retinal prosthesis for blindness induced by retinitis pigmentosa and macular degeneration; the use of human psychophysical techniques to develop optimal image acquisition and stimulation protocols for retinal prosthetic devices with limited numbers of microstimulator electrodes; the study of lateral brightness and chromatic adaptation in the human visual system; and the search for the fundamental origins of layering throughout the human visual and cortical systems.
