Latest Patents
One of John Schaefer's latest patents is a system for detecting ice or snow on surfaces that specularly reflect light. This innovative system detects the presence of a polarization-altering substance on a specular surface by transmitting light from a single strobed light source to the surface. The transmitted light is then received back from the surface, where the intensity is measured in both an optical non-isolator state and an isolator state using the same detector. The non-isolated return light is delayed for a specific period before measurement. The isolated and non-isolated intensities are converted to logarithmic form, range corrected, and compared to reference data for the specific surface being investigated. This process allows for the detection of the polarization-altering substance while compensating for attenuation and backscattering effects. By utilizing different intensities of transmitted light, the dynamic range of the system is significantly increased.
