Abstract

The acousto-optic tunable filter (AOTF) was demonstrated to be an effective and economical means for implementing a compact ( field deployable ) near-infrared Acousto-Optical Spectrometer (AOS) for quality assessment of small fruits. The design and construction of this device including design limitations and problems are presented. The characterization of the AOTF and the AOS system design address the areas of radiation source selection optical alignment optical design signal detection computer control and system testing. This work confirmed the operating specifications and limitations of the AOTF as described by the manufacturer.
