Laser treatment of hemangiomas using spectroscopic feedback : the "smart scalpel"
… instruments with embedded feedback control systems are uncommon. To improve the effectiveness of microsurgical techniques, we are presently developing a semi-autonomous robotic surgical tool (called the "Smart Scalpel") as an alternative approach to treatment of skin hemangiomas like nevus …

Nonlinear Microscopy for Materials Analysis and Clinical Pathology
From understanding biological systems to characterizing materials, microscopy has facilitated the analysis of micro and nanoscale systems across scientific disciplines. The optical transparency of different biological features allows pathologists to relate what they see on a microscope slide to …

Demonstrating Reflectarray Behavior At Infrared
… passive, planar microstrip antenna devices designed for reflected phase manipulation at each individual antenna element making up the array. By varying the phase response across the surface with the antenna elements, reflectarrays allows a planar surface to exhibit electromagnetically an …

Computational tools for monitoring neural connectivity using calcium imaging
… have been made that allow for facilitated optical delivery, activation, and recording of neural dynamics. These include fiber-optic cables for targeted optical delivery, genetically encoded calcium indicators (GECI) for optically measuring signaling dynamics, fiber bundles for spatially …

Small displacement measurement in ultrasound: quantitative optical noncontacting detection methods
… developed interferometric sensors are: 1) an optical system design for the detection of the surface acoustic wave (Rayleigh wave). The technique is based on the Fourier analysis of coherent light and diffraction imaging properties of an illuminated grating; 2) the design and construction of a …

Implications of Fiber Nonlinearities on Coherent Optical Fiber Communications
A primary objective of optical system design is to satisfy the ever-increasing capacity demand for communication services. Fulfilling this target by increasing the cardinality of modulation formats is at the expense of a reduced system tolerance to transmission impairments with the capacity …

Computational spectral microscopy and compressive millimeter-wave holography
… spectral imager that employs a compressive optical architecture to record a spectrally filtered projection</p> <p>of a 3D object data cube onto a 2D detector array. Two nonlinear and adapted TV-minimization schemes are presented for 3D (x,y,λ) object estimation from a 2D compressed …
