SUMMARY:SOLUTIONS TO LINEAR PROBLEMS IN ABERRATED OPTICAL SYSTEMS
DESCRIPTION:Featuring William Shain\n\nPart of the PhD Final Oral Exams.\n\
	nExamining Committee: Bennett Goldberg\, Jerome Mertz\, David Campbell\, St
	eve Ahlen\, Thomas Bifano\n\nAbstract:\n\nOne of the greatest challenges in
	 understanding any physical system is extracting as much information as pos
	sible. In optics\, the laws that govern the interaction of a system with li
	ght are frequently linear: Maxwell’s equations lead to linear wave equati
	ons\, and in general one can write the evolution of the quantities of inter
	est as a linear propagation in space and time. This linearity imposes a con
	straint on how one recovers information about an object of interest; for ex
	ample\, one can expand the field-of-view by taking multiple images (reducin
	g the total framerate) or by lowering the numerical aperture (reducing the 
	resolution). In each case\, one aspect of information is sacrificed for ano
	ther. Therefore\, one can efficiently probe a system through optical means 
	by carefully choosing what aspects of the light are measured\, depending on
	 the problem of interest. This can be attained through direct manipulation 
	of the optical propagator\, by using a Spatial Light Modulator to perform p
	hysical linear transformations on the light field. In this thesis\, I demon
	strate the usefulness of a MEMS Deformable Mirror (DM) in implementing the 
	necessary linear transformation\, and apply the methodology to three system
	s of interest: recovering imaging capabilities in porous rock\, expanded im
	aging of neuronal activity in brain tissue\, and high-throughput particle i
	dentification in label-free flow cytometry. In each case\, I show how caref
	ul control of the light travelling through the microscope allows for optimi
	zed recovery of the desired information.
