Test 2 will be completed in-class, without reference material. It will be a 1-hour test.

Without reference materials, students should be able to:

Find the position of the minima in the Fraunhofer diffraction pattern of a single slit. | |

Describe the Fraunhofer diffraction pattern of a circular aperture and comment on how this limits the resolving power of optical instruments. | |

Calculate the maximum resolution of optical instruments | |

Solve simple problems involving two-slit and multiple-slit interference. | |

Work problems involving interference from thin films. | |

Define temporal and spatial coherence. | |

Describe the essential features of a LASER. | |

Describe how images can be processed by manipulating their Fourier transform. | |

Describe the essential features of optical processing. | |

Define the point-spread function and elaborate on the convolution theorem. | |

Define linear, elliptical, and circular polarization and how to produce linear and circular polarized light beams. |

Review the notes, assignments 6-9, and in-class problems 8 - 12.
