    Assigning Denavit-Hartenberg frames to RPR robotic structure

    Homework Statement I'm required to assign co-ordinate frames to an RPR robotic structure, using the Denavit-Hartenberg notation. Homework Equations N/A The Attempt at a Solution I've made the following two attempts at the problem, but i aren't sure which, if any, is correct...

    How do I extract intensity values from a diffraction grating image in MATLAB?

    Homework Statement Hi. I'm attempting to find the fringe visibility of an interference pattern from a diffraction grating, using MATLAB. I have an image of this pattern, and have used the following code so far in MATLAB: myimage = imread('IMG_0166.JPG') image = rgb2gray(myimage); imshow(image)...

    Diffraction - Calculating Width of a Slit

    Thanks for the reply. It was practical experiment that i did, and we were required to take photos of the results. A red laser was used, so would you suggest i use the wavelength for red light?

    Diffraction - Calculating Width of a Slit

    Homework Statement I am required to calculate the width of a single slit. I have known distance, L, between the observation screen and the slit, and photo images were taken of the resulting waveform. However, the wavelength is unknown, therefore making many of the equations I'm attempting to...
