2010 Computer Generated Holography (CGH) and Diffractive Optical Element (DOE) Workshop

March 16 - 18, 2010

Co-Sponsored by SPIE

CGH design spans decades of applied and theoretical research.  Diffractive Optical Elements (DOE) are CGHs used in optical systems. Fabrication of these devices has traditionally been time-consuming, using binary photomasks and semiconductor foundry resources. The purpose of this workshop is to provide participants with a hands-on learning opportunity for design and fabrication of these devices using the Maskless Lithography Tool (MLT) at the College of Optical Sciences. Through a series of lectures, computer training, and laboratory experiments, participants will be exposed to processes needed to design and build physical devices.

Learning objectives

Participants who successfully complete this three day course will be able to:

• Specify, analyze, design and test properties of Diffractive Optical Elements (DOEs)

• Specify, analyze, design, and test properties of CGH display holograms

• Design and use DOEs for optical testing applications

• Describe basic fabrication procedures used in fabricating CGHs and DOEs with maskless grayscale lithography

• Fabricate several types of CGHs and DOEs using the MLT

Intended audience

The course is geared towards scientists, engineers, managers, and researchers interested in exploring fundamentals of Computer Generated Holography, Diffractive Optical Elements, and Maskless Grayscale Lithography who want to gain hands-on, working knowledge in this field. A strong undergraduate-level mathematical background and a basic knowledge of optics are helpful.

Program overview

Classes are divided into lecture and laboratory sessions, where each day covers a different topic. The laboratory involves hand-on training in fabrication and testing of CGHs. Software written in the Matlab© language is provided with a one-year license agreement as part of the course. Class are scheduled to be held in the world-famous College of Optical Sciences on the beautiful University of Arizona campus in Tucson, Arizona. Class size is strictly limited to provide a quality learning environment.
