optical devices using linear (ray) optics and Fourier optics as well as optical
metrology. Hands-on practice is provided
by extensive laboratory activities.

Rationale for Introduction of this
Course
This course is a
prerequisite for Biophotonics course (ENSC 476-4) and is an important component
of the “Biomedical Signals and Instrumentation” Concentration of the Biomedical
Engineering curriculum. It will also be
beneficial for Engineering Physics option students. The
It is an elective course
in the Biomedical Signals and Instrumentation concentration of the BME
curriculum. Probable enrolment: about 20
students
Scheduling
and Registration Information
Indicate Semester and Year this course would be first
offered and planned frequency of offering thereafter.
This course would first
be offered in Spring 2008. Thereafter it would be offered annually in the
Spring semester.
Which of your present CFL
faculty have the expertise to offer this course? Will the course be taught by
sessional or limited term faculty?
Andrew Rawicz, Glenn
Chapman and any new faculty hired in this area.
It will be taught by tenure-track faculty.
Are there any proposed student
fees associated with this course other than tuition fees?
No.
Is this course considered a
`duplicate' of any current or prior course under the University's duplicate
course policy? Specify, as appropriate.
No.
Resource Implications
Note: Senate has approved
(S.93-11) that no new course should be approved by Senate until funding has
been committed for necessary library materials. Each new course proposal must
be accompanied by a library report and, if appropriate, confirmation that
funding arrangements have been addressed.
Provide details on how
existing instructional resources will be redistributed to accommodate this new
course. For instance, will another course be eliminated or will the frequency
of offering of other courses be reduced; are there changes in pedagogical style
or class size that allow for this additional course offering?
This course is proposed
for a new engineering program “Biomedical Engineering”. We have no existing instructional resources
to accommodate this course, so we plan a new faculty position funded by DTO.
Does this course
require specialized space or equipment not readily available in the department
or university, and if so, how will these resources be provided?
Yes. A new laboratory for this (and Biophotonics)
course will be created. A laboratory is
an important components of this course.
Additional financing for this course will be obtained from DTO.
Does this course
require computing resources (e.g. hardware, software, network wiring, use of
computer laboratory space), and if so, how will these resources be provided?
Yes. Specialized software for optical systems
modeling and simulation (Zemax and Optiwave) will be used. These packages will be purchased from DTO
funds.
