The system has optical collecting unit (6) including mirrors (7, 8) arranged for forming an intermediate image. An optical relay (10) is arranged for correcting aberrations of the image to obtain a corrected monochromatic final image. The relay has front and back convergent optical blocks (11...
The unit allows the target object to be aimed at and allows its angular deviation with respect to the line of sight to be determined by means of a single optical system, as a result of which adjustment devices are rendered superfluous. <IMAGE> 展开 ...
a proximity sensor module (10), for optical distance sensing includes a target surface (25) having a non-uniform design including a high-reflectivity region and a low-reflectivity region for light of a particular wavelength. The position of the target surface (25) is displaceable within the ...
FUNCTIONALTESTOPTICALtestingTARGETA novel optical testing target(OTT) with three degrees of freedom(DOFs) is proposed for measuring the tracking performance of a photoelectric theodolite. The main components, such as the azimuth axis system, the pitching axis system, the linear motion system, and ...
Credit Suisse: maintain SunYu optical's "outperform the market" rating and raise its target price by 28.2% to HK $273
these materials must initially possess optical properties, including energy absorption and emission, as well as high quantum yield and extinction coefficient [64]. The morphology, atomic configurations, and nanostructure’s exposed surface area are related to the efficient transfer of charge carriers duri...
Summary The generalization of Watson's theory of the optical model potential to the case of completely antisymmetrized wave functions of theA+1 particles system given by Rollnik is discussed. The lowest order corrections to the nuclear potential in the Takeda and Watson formulation being of the ...
