2. What is in this ???
What is CAD
Why go for CAD tools
What are the Different Propagation Models in
Optical CAD
Classification of CAD tools
The different CAD Tools
Conlusion

3. What is CAD???
Computer Aided Design (CAD) is the use of
computer systems to assist in the creation,
modification, analysis, or optimization of a design

4. Why go for CAD tools?????
Reduces human error
Availability of standard devices in library
Easier and cheaper to modify designs
Direct linking with Computer Aided
Manufacture(CAM) is possible
Simulation helps in detecting and correcting
errors before implementation

5. What are the Different Propagation Models
in Optical CAD???
Ray Propagation
- Direction, position and angles
Gaussian Propagation
- 9 scalar parameters(z0,x,y,z,etc..)
- Fast simulation (no integration)
- Limited diffraction modeling
Scalar Optics
- 2D complex wave front
- Propagation by summation of wave fronts
Vector Analysis
- Intensive computation, Boundary Element
