Processing of laser interferometric signals for small displacement measurements

Creator:

Peng, Gwo-sheng

Abstract:

Algorithms for analyzing laser interferometry signals were developed and adopted to the computer based processing of small displacement measurements. These methods, matrix operation approach and fixed parameters approach, are based on signal phase calculation and are able to replace complex fringe counting electronic circuits. The matrix operation provides an approach...

The design of an aquatic insect imaging device as part of a system to automate insect classification for biomonitoring

Creator:

Sarpola, Matt J.

Abstract:

Population counts of aquatic insects are a valuable tool for monitoring the water quality of rivers and streams. However, the handling of samples in the lab for species identification is time consuming. An aquatic insect imaging device was designed as part of a system to automate aquatic insect classification and...
