Title: “Precision Interferometric Measurements in Non-ideal Environments”

Speaker: Dr. James Wyant.

Abstract: Precision optical components are essential for modern photonics systems. Modern electronics, computers, and software have made it possible to greatly improve the testing of optical components and optical systems and the resulting improvements in the new optical instruments and devices we use are evident. Until recently a major limitation of interferometry for precision metrology was the sensitivity to the environment. In recent years many techniques for performing high quality interferometric measurements in non-ideal environments have been developed and new techniques are being introduced all the time. This talk discusses some of the different techniques for reducing the effects of vibration and atmospheric turbulence on interferometric measurements. The application of these techniques for the measurement of surface vibration, the testing of optical components including large astronomical optics, the phasing of segmented optical components, and the measurement of deformations of diffuse structures will be described.

Title: “Computational optical sensor systems: Rethinking the traditional measurement paradigm”

Speaker: Dr. Michael Gehm

Abstract: Computational sensing is a sensor design methodology that rethinks the standard paradigm of direct, isomorphic sampling. Combining concepts from experimental design, signal multiplexing, information theory, detection and estimation theory, modal analysis, and linear system theory, the field takes advantage of modern computational resources to recast measurement as solution of an inverse problem that is specific to a specific sensor task. The result is a greatly-expanded system design space containing new architectures with superior performance for a variety of applications.

Lecture topics:

  • Mathematical sensor measurement model and noise
  • System and physical constraints
  • Codes and multiplexing
  • Linear algebra of measurement
  • Task-specific systems
  • Nonlinear approaches (including compressive inference)
  • Case studies in computational imaging and spectroscopy

Title: Nanophotonics

Speaker: Dr. Joseph Haus

Abstract: This course covers aspects of nanophotonics with emphasis on novel materials (photonic crystals, metamaterials and plasmonics).  Fabrication and characterization issues at the nanoscale will also be addressed.  Linear and nonlinear propoerties of materials for applications such as new coherent sources and super-resolution will be discussed.

Title: Design Concepts and Applications of Readout Integrated Circuits (ROICs)

Speaker: Dr. Payman Zarkesh-Ha

Abstract: Over the years the quality and performance of infrared cameras has been significantly improved. For instance, multi-color infrared imaging is now a vital tool to enhance the quality of infrared image. These improvements are largely due to the advancement in readout integrated circuits (ROICs) used in such imaging systems. The main objective of this short course is to present the basic design concepts and to demonstrate the applications of readout integrated circuits (ROICs) in real imaging systems.
The course contains two parts: (a) in the first part, the basic concepts of readout circuits for infrared imaging systems will be discussed. In addition, the requirements and challenges of designing a practical ROIC will be presented. An example of real ROIC test chip using CTIA with large dual bias range of +/- 5V designed with the high voltage 0.35um CMOS double poly, four metal-layer TSMC manufacturing process will be presented. (b) in the second part of this course, some applications of ROIC will be demonstrated. The applications includes: an intelligent ROIC for integrated spatio-temporal image processing and ROIC for visible light communication (VLC) in smart lighting environment.
The topics of this short course are: ROIC overview, ROIC active components, ROIC design constraints (noise, dynamic range, unit cell area, and well capacity), ROIC design techniques (CTIA, direct injection, and buffered injection), ROIC applications in imaging systems, ROIC applications in visible light communication (VLC)
