A concentric glass spherical dome was usually chosen as the transparent window mounted in front of the optical lens in an image seeker. However
optical ray had to change its direction when propagating through the dome due to refraction unless passing through the center of the dome
which demanded gimbal point coincide with the center of the dome exactly. In fact
gimbal point displacement could not be eliminating due to fabrication
assembly and vibration
therefore the optical axis pointing error generated. In this paper
the effect of gimbal point displacement on optical axis pointing precision in an image seeker was analyzed
and the theoretical expression of the optical axis pointing error was derived based on geometric optics
and the error dynamics was explored by numerical. Take a visible light image seeker as a case
the thickness of concentric glass spherical dome was 8mm and the inner radius was 72mm
and the optical axis pointing errors varying dynamically with the look angle and the gimbal point displacement were shown in graph. When the gimbal displacement was 0.11mm
the maximum optical axis pointing error was 0.054mrad that is equal to the instantaneous field of view (IFOV) corresponding to the camera system whose focal length was 120mm and pixel size was 6.5m. Furthermore
with the gimbal displacement increasing
the optical axis pointing error increased linearly. The analyzed results provided a theoretical basis for the displacement range
which had to be limited strictly in the gimbal design process. 2011 IEEE.

A new design of compound Fresnel-R concentrator is presented which is composed of two lenses: a primary lens (Fresnel lens) that works by total internal reflection at outer facets but refraction at inner facets
and a secondary lens that works by refraction. In contrast to previous Fresnel lens concentrator
this design increases the acceptance angle
improves the irradiance uniformity on the solar cell
and reduces the aspect ratio significantly. Another outstanding advantage of this concentrator is the fact that it mainly works by performing total internal reflection
reducing chromatic dependence as well as Fresnel losses. An optical efficiency more than 80% can be achieved. Moreover
in order to reduce the influence of manufacture accuracy and to increase the optical efficiency further
the central part of the bottom of the secondary lens which directly adhered to the solar cell is designed as a cone-shaped prism to collect the sunlight that doesn't reach the solar cell. 2010 SPIE.
