On Fresnel-Based Single and Multi Spectral Sensors for Insects’ Wingbeat Recording

This paper reports on optoelectronic sensors and their associated recorders that are based on Fresnel lenses and record the wingbeat of insects in flight. We present a novel single-band sensor and, a low-cost multispectral sensor. This work belongs to a broader context of applications that relate to automated insect surveillance of insects of economic and hygienic importance.
