We present a microsteering device for laser beam, aimed at telemetry and ob
stacle detection applications. The operation range scales from visible to i
nfrared wavelengths owing to silica structures, etched on silicon substrate
. The design combines a steering system of microlenses driven by electrosta
tic actuation. This design, associated with silicon surface micromachining
technology enables the production of more than 700 chips on a 100 mm diamet
er wafer. Furthermore, we highlight the simplicity of the process as the me
chanical structure and optical axis move in the substrate plane. This paper
describes the structure, technological process sequence and experimental r
esults of the developed LD-scanner. (C) 1999 Elsevier Science S.A. All righ
