3D Printing and a Smartphone Create an Inexpensive, Compact Interferometer https://ift.tt/2DenNs6 Smartphones serve many functions, including that of scientific instruments. With a little tinkering and 3D printing help, makers have turned smartphones into things like microscopes, and in a paper entitled “Design of a 3D printed compact interferometric system and required phone application for small angular measurements,” a pair of researchers document how they used 3D printing and a smartphone to create an interferometer, a scientific instrument that takes precise measurements through the interference of two beams of light.
The opto-mechanical components for the system were all developed using ZW3D CAD software and then 3D printed on a Raise N2 Plus 3D printer. Optical components such as a lens and pinhole were mounted to the 3D printed components. The phone itself is equipped with a 13 megapixel count CMOS sensor with high resolution. An Android application was developed for onboard fringe processing and automatic evaluation of angular rotation of the glass slide.
3D printing has been used to create all sorts of low-cost laboratory equipment, including reactors, drug testing systems and much more. The purpose of the researchers’ paper was to demonstrate that a complex interferometer could be created using accessible, inexpensive means – a smartphone and 3D printed components. Not only is the device inexpensive, it’s user-friendly and compact, making it portable enough to take anywhere in the field. These are the advantages of 3D printing – the ability to take complex tools and reduce them to only a few components, drastically cutting back on cost and size. Authors of the paper include I. Hussain and P. Nath. Discuss this and other 3D printing topics at 3DPrintBoard.com or share your thoughts below.
