Design of Super-Wide-Angle Mobile Phone Camera Based on Concentric Lens
One kind of 13 mega-pixel and super-wide-angle mobile phone camera is designed based on concentric lens and the parameters of the mobile phone camera that meet the industrial production requirements are obtained. This camera is composed of 4 concentric lenses with a focal length of 3.3 mm, a F-number of 1.83, a field of view (FOV) of 100°, and a total length of 5.18 mm. The research results show that, at the Nyquist frequency of 223 lp·mm -1, the modulation transfer function (MTF) value is larger than 0.58 in the 0.7 FOV and that in the whole FOV is larger than 0.50. At 446 lp·mm -1, the MTF value is larger than 0.30 in the 0.7 FOV and that in the whole FOV is larger than 0.17. The root-mean-square (RMS) radius of each FOV is less than 2.3 μm and the relative illumination value is larger than 0.65 in the full FOV.
