A Custom Reflectance Goniometer and its Usage in the Development of Gain Reflectors for Electronic-Paper Applications
A modified goniometer has been successfully developed and used to characterize novel electronic-paper (e-paper) devices. A power meter, in conjunction with a DC servo motor, was controlled within a Labview program to automate the collection of data reflected light off of e-paper substrates. Next, …
