Optical grade thick diamond films are polished on two sides by electron discharge machining (EDM) are with a mechanical method. The infrared transmittivities of Y2O3/diamond films are investigated in detail. Results indicate that the average infrared tran
In optical scanning holography, one pupil produces a spherical wave and another produces a plane wave. They interfere with each other and result in a fringe pattern for scanning a three-dimensional object. The resolution of the hologram reconstruction is
This letter presents a correlation tracking algorithm based on edge detection, in allusion to the phenomenon that the target is susceptible to interference in long-wave infrared image. Firstly, the collected imageis processed by median filtering to remove
