Registration Information

Enrollment was limited to 20 participants. Registration began on November 6, 2008 and ended when all seats were filled.

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

Program overview

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

Enrollment included Lectures Labs Course materials Coffee breaks Variety of lunches Laptops were provided at no cost to the participants Software including a one-year Matlab license Note: Students did not receive the OptiScan software license agreement. Student reviews from the 2009 workshop "Well organized, well run. Both the lecture and the labs went very smoothly, hitting the important topics, keeping on schedule and integrating concepts from lecture to lab." "Hands on experience and actual labs rather than just tours were very helpful and appreciated by everyone." "The food is great." "The level of information was appropriate and practical concepts/concerns about the topics were well demonstrated." "A good combination of lectures and labs."
