AI Article Synopsis
- A new type of differential Hartmann sensor has been developed for accurate and precise optical system measurements without needing extensive background on the illumination wavefront or measurement geometry.
- The sensor can be applied effectively to both zonal and modal testing of lenses, making it versatile in optical assessments.
- A dual-camera version of the sensor is also introduced, which allows for faster optical testing, enhancing its efficiency in practical applications.
Article Abstract
A novel differential Hartmann sensor is described. It can be used to determine the characteristics of an optic accurately, precisely, and simply without detailed knowledge of the wavefront used to illuminate the optical system or of the geometry of the measurement system. We demonstrate the application of this sensor to both zonal and modal optical testing of lenses. We also describe a dual-camera implementation of the sensor that would enable high-speed optical testing.
