wyant.optics.arizona.edustructed irradiance. Thus, the irradiance produced by the first Fresnel zone is equal to 4 times the irradiance obtained with a clear aperture. As the equation shows, for odd numbers of Fresnel zones present i@ PD = 4ioo@ PD (6) For even numbers of Fresnel zones present the Fresnel zones cancel one another and the on-axis irradiance is zero.

The Fresnel Biprism - Trinity College Dublin
www.maths.tcd.ie2.2 The Fresnel Birpism A Fresnel Biprism is a variation on the Young’s Slits experiment. The Fresnel biprism consists of two thin prisms joint at their bases to form an isosceles triangle. A single wavefront impinges on both prisms; the left por-tion of the wavefront is refracted right while the right segment is refracted left.

In a similar way, we deal with the Bessel function before it makes its appearance in this book (see Ch. 5). This is because Ai(x) and Bi(x) can be expressed in terms of the Bessel function, and Airy Functions 75
