415/515

 

OPTI 415/515  Optical Specifications, Fabrication, and Testing (3) I. Specification of optical components including tolerancing and drawing preparation, material properties, performance metrics; conventional fabrication methods for refractive and reflective optics; optical testing including interferometric testing of surface form and finish, special techniques for aspherics, error analysis, test calibration; and testing of optical systems.

This will be offered as a distance learning class.

 

The lab class 415:/515L is strongly recommended.

 

Grading :

OPTI 415 (undergraduate)

Grades in this course will be derived half from exams (two mid-terms and a final) and half from regular homework, reports, and quizzes. The homework solutions will typically be submitted as complete informal technical reports. These will be graded on presentation as well as content.

50% homework

25% midterm exams

25% final exam

 

OPTI 515 (graduate)

For graduate credit, graduate status and additional work will be required. In addition to the homework and exams, two additional reports will be assigned over the semester. These will require independent research or design. One class presentation will be required.

40% homework

20% midterm exams

20% final exam

20% Independent reports/presentation

 

OPTI 415L/515L Optical Specifications, Fabrication, and Testing Laboratory (1) I

Practical measurement techniques for optical surfaces, components and systems, comparing measurement data with specifications, relating fabrication issues with test methods. (co-requisite OPTI415 or OPTI515)

 

Students work in small groups for one 3-hour lab session per week.

 

Grading :

415L, undergraduates: 100% from lab notebooks

515L, graduate students: 75% from lab notebooks, 25% from project/report.

Introduction

(4) Optical systems

Define metrics for imaging system performance and present concepts and professional techniques for measuring them.

Focal length, principal planes and distortion

Review image formation.  Define first order parameter using Newton and Gauss definitions.  Show how these parameters are measured for real systems.

Focal collimator

Nodal slide

Imaging distortion

Image sharpness

Define metrics that quantify image sharpness.  Show concepts and professional techniques of measuring these metrics for real systems.

Use of calibrated collimators

PSF, Encircled energy, Star test,

Knife edge

MTF, definition and measurement

Scanning pentaprism

Wavefront quality

Present rationale for using WF as performance metric.  Show concepts and professional techniques of measuring these metrics for real systems.  In particular, interferometry is covered here.Diffraction limited PSF, Strehl, MTF

Zernike polynomials

Interferometry, autocollimation testing

Commercial interferometers, and issues

Introduction to interferometry
Fizeau, TG, Shack cube
Phase shift interferometry

Vibration insensitive WF measurements

SPSI
Common path interferometers
PDI, scatterplate, shearing

System alignment

Introduction to concepts and methods of system alignment.  Using system tests to discern alignment errors.

System testing, qualification vs. process

Effects of misaligned optics

compensation

Sensitivity

Introduction to test methods for parameters that affect sensitivity, rather than resolution.

 

Class Attendance:

Class attendance is required. Just as you are expected to show up every day for a job, you are expected to be in class and to participate in class. Absences and late arrivals will affect your grade.

Textbooks:

There is no textbook for this class. You are expected to read an average 50 pages a week from journal articles and book chapters.

  • Selected journal articles and book chapters
  • Supplemental instructor notes

 

Academic Integrity
According to the Arizona Code of Academic Integrity
(http://dos.web.arizona.edu/uapolicies/cai2.html), “Integrity is expected of every student in all academic work. The guiding principle of academic integrity is that a student’s submitted work must be the student’s own.” Unless otherwise noted by the instructor, work for all assignments in this course must be conducted independently by each student. CO-AUTHORED WORK OF ANY KIND IS UNACCEPTABLE. Misappropriation of exams before or after they are given will be considered academics misconduct.

Misconduct of any kind will be prosecuted and may result in any or all of the following:
* Reduction of grade
* Failing grade
* Referral to the Dean of Students for consideration of additional penalty, i.e. notation on a student’s transcript re. academic integrity violation, etc.


Students with a Learning Disability
If a student is registered with the Disability Resource Center, he/she must submit appropriate documentation to the instructor if he/she is requesting reasonable accommodations. (http://drc.arizona.edu/learn/test-accommodation.html).

The information contained in this syllabus, other than the grade and absence policies, may be subject to change with reasonable advance notice, as deemed appropriate by the instructor.
