Optical Micro-scanning Reconstruction Technique for a Thermal Microscope Imaging System

摘要

Thermal microscope imaging system can achieve the detection of sub-tle targets by temperature changes, which has extensive utility value in some respects that need detailed thermal analysis. Due to the mechanical preparation of the system, working vibration, external environment and other factors of inter-ference, which will affect the precision of the micro-scanning system, Causing the micro-displacement of the four images acquired by the system deviate from the standard position. Therefore affecting the quality of subsequent image recon-struction. To minimize the impact of these factors, a micro-scanning reconstruction technique based on local gradient interpolation was proposed. The simulation and experiment demonstrate that the method can decrease the system micro-scanning error and enhance image reconstruction quality.
