We present a novel technique for thermal imaging in capitalisation on the Hartmann wavefront sensing technology for purposes of 3-D sensing. The issues of reflection induced noises, diffuse nature of thermal radiation, and directionality of emissivity, which might affect the results of thermal Hartmann wavefront sensing, are also discussed.
Shark-Hartmann Wavefront sensor splits the incident wavefront into many subsections and transfers the distorted wavefront detection into the centroid measurement. The accuracy of the centroid measurement determines the accuracy of the Shack-Hartmann Wavefront Sensor. A lot of methods have been presented to improve the accuracy of the wavefront centroid measurement. However, most of these methods are...
