To the characteristic of the ultraviolet CCD (UV ICCD)  technique of the linearity measurement of the UV ICCD camera is studied based on the theory of radiometry. Approach of linearity measurement is discussed  and a kind of measurement system of the UV ICCD has been developed based on the method of neutral density filter. It is very important that the transmittance of the filter is independent of the wavelength in the method of neutral density filter. Black metal screen mesh with different transmittance is used in our system  and calibration of the filters' transmittance in different working positions has been done. Meanwhile  to assure the uniform of the received radiation on the target of the detector at any test points  an integrating sphere is placed behind the neutral filter to balance light. The whole measurement system mainly consists of a deuterium lamp with high stabilization  the attenuation film with transmission  integrating sphere  optical guide and electro-shift platform. Auto control is realized via special software during the test. With this instrument  the linearity of the UV ICCD was measured. Experimental results show that the nonlinearity of the UV ICCD under fixed-gain is less than 2% and the uncertainty of measurement system is less than 4%. 2010 Copyright SPIE - The International Society for Optical Engineering.

In order to realize real-time auto-focusing for theodolite  lens-apart method was designed with the corresponding math model built and analyzed. An Object beam splitted after the first image surface of the theodolite traveled through two dialyte lens and then was imaged on CCD. The distance between two spots when exactly focused was set as the calibration value  and the relationship between defocus distance and spot offset was given. The influence of tracking center shift and divergence angle etc. on focusing accuracy was analyzed. Compared with the traditional focusing method  this scheme has a higher accuracy  faster calculation  higher tolerance for environment temperature and a simpler construction. The experiment result exhibited a resolution higher than 0.056mm  which shows a bright engineering application prospect for this method. 2009 SPIE.
