Characterization of Image Receivers for Optical Wireless Location Technology Arafa, Ahmed Tarek; Jin, Xian; Bergen, Mark; Klukas, Richard; Holzman, Jonathan F.

Abstract

In this work, image receivers are characterized to address the challenges of indoor positioning with optical wireless location (OWL) systems. Image receivers are studied according to their field-of-view (FOV) characteristics: the first image receiver uses a wide-FOV (95°) microlens; the second image receiver uses an ultrawide-FOV (130°) microlens. An angle of arrival (AOA) characterization of the image receiver is used to quantify azimuthal, φ, and polar, θ, angles of incident light from optical beacons. A dilution of position (DOP) characterization is used to quantify geometrical effects of the optical beacon distribution. It is found that the ultrawide-FOV microlens (with a mean positioning error of 1.5 cm) can better image widely separated optical beacons, and thus operate at a lower DOP, compared to the wide-FOV microlens (with a mean positioning error of 3.2 cm).
