Description

Spectrum Analyzer iOS App, will need to give permission to allow the App to have permission to use your camera and file system when prompted Physical Apparatus A diffraction grating to be place in front of the camera Light source such as a multi propose laser pointer iPhone or iPad with the App installed Use Select one of the three sources of image Front Camera /Back Camera/File Manager If the calibrated length between 2 points on the image is to be used, for example, distance between zero order length and the first order diffraction pattern of the red wavelength is approximately 650 nm, then select the radio button calibrated to input a known length. Move the square start end to re position the start of known calibrated start point and drag the arrow head to the end of the known length. Similarly, re position the start and end of the free line spectrum to analyze the pixel perceived brightness where the start is BLUE =400 and end is RED =700 nm The play/pause button will start or stop the calculation of the free line pixel perceived brightness along the line.
