Latest Patents

One of his latest patents is a nulling optical bridge designed for the measurement of changes in reflectivity and/or transmissivity. This invention includes light means for supplying light and splitter means for dividing the light into two beams. The first beam is directed to a surface with a parameter to be measured, while a first photodetector captures the reflected or transmitted light, generating a signal indicative of its magnitude. A second photodetector measures the second light beam, and an electronic balancing circuit adjusts the signals to equal magnitudes, providing a compensating signal when the parameter varies. This innovative design allows for accurate monitoring of the parameter's magnitude.

Another significant patent by Wilman is a nulling optical bridge for contactless measurement of changes in reflectivity and transmissivity. This device can precisely measure the difference in the relative power of multiple light beams. It operates by splitting an illumination source into several beams, with one beam traversing the sample whose characteristics are being measured. A rotating polarizer is utilized to equate the intensity of the variable and non-variable beams, ensuring accurate measurements under feedback servo control from a photodetector.
