MATLAB for Beginners

Christopher R. Doerr

The MATLAB 5 Handbook, by Darren Redfern and Colin Campbell, is an introduction to the MATLAB (matrix laboratory) programming language for beginners, as well as a reference book for experienced users.1 It is, according to the authors, "written for all MATLAB users, regardless of their discipline or field(s) of interest." MATLAB is an interpretive (not compiled) programming language based on arrays and matrices, and has many powerful, built-in, mathematical, and graphing functions. more>>


Diffraction Gratings, Part 1

Masud Mansuripur, Lifeng Li, Wei-Hung Yeh

The goal of the present article is to describe some of the basic properties of gratings, and to point out through several examples the complex behavior of these devices. These examples are by no means comprehensive, but they should make it amply clear that there is no simple way to predict a grating's diffraction efficiency. more>>


Fast IR Fisheye Lens with Hyper-Hemispherical Field of View

J. Brian Caldwell

This month's patent design is a fisheye lens for long wavelength IR (8-12 μm wavelength range) that covers a full field of 270° at an astonishingly large aperture of f/0.7. This combination of field coverage and aperture is unprecedented, but in spite of the extreme specifications, the design is quite simple, consisting of only four germanium elements. The design would provide an interesting challenge to a manufacturer because the concave surface of the negative meniscus front element is hyper-hemispherical more>>
