Triangles Make a Better Sensor
Dr. Alexandre D. Soukhomlinoff
A number of applied optical measurement tasks require measuring linear displacement or elevation of a radiant source.
Many typical photodiode arrays designed for this purpose use 35-, 46- or out to 1024-element sensors that are linearly dispersed along the device. However, using this type of sensor in an application is not always the best technical solution for several reasons…
