Abstract:
The goal of this project is to establish the feasibility of a new technique to
obtain three-dimensional imagery. The innovative concept is the implementation of
a non-mechanical optical scanning technique consisting of a modulated laser and a
compact, high-frequency video camera with no moving parts. The resulting three-dimensional
imager would be about one-tenth the size and weight and consume much less power than
comparable mechanically driven laser scanners. It would also be more rugged and have
higher reliability and lower production costs.
The Phase I feasibility study has shown that the design of an electronic scanning
sensor, using an image dissector photodetector, is possible and has provided a preliminary
optical, electronic, and mechanical design concept. Preparation of a system design
concept provided the means for predicting the performance of the sensor as well as
the size, weight, and power consumption estimates. This three-dimensional imaging
scanner would have performance suitable to satisfy the requirements of the NASA Goddard
Space Station Orbital Replacement Unit grasping task.
Potential Commercial Application:
Potential Commercial Application: Applications of the three-dimensional sensor are
in enhanced autonomous robotic assembly and bin picking, quality control, mensuration,
vehicle guidance, and teleoperated robots used in hazardous environments including
hazardous waste, nuclear-contaminated sites, and bomb disposal.
