• However, incoherent imaging is insensitive to phase objects • Polychromatic imaging introduces further blurring due to chromatic aberration (dependence of the MTF on wavelength)
Consider a binary amplitude grating, with perfect contrast m=1, period Λ=10µm, duty cycle 1/3 (33.3%), illuminated by an on-axis plane wave at wavelength λ=0.5µm. The 4F system consists of two identical lenses of focal length f =20cm.
Wave Optics (physical optics) treated in the second half of the class: - Emphasis on analyzing interference and diffraction - Gives more accurate determination of light distributions
The amplitude of a wave is represented by the length of a “vector” on an Argand diagram. The phase of the wave is represented by the angle of the vector relative to the
11 Ιαν 2023 · We begin our study of waves in this first unit of Physics 7C with an introduction to waves and then a thorough development of the harmonic plane wave model, which we will use extensively to model and understand a wide variety of wave phenomena.
The Simple Wave Simulator Interactive provides the learner with a virtual wave machine for exploring the nature of a wave, quantitative relationships between wavelength, frequency and speed, and comparisons between transverse waves such as those traveling through a rope and longitudinal waves such as sound.
Adjust frequency and amplitude, and observe the effects. Hear the sound produced by the speaker, and discover what determines the color of light. Make waves with a dripping faucet, audio speaker, or laser!
