| | The image quality valuation of home-made large size zoom TV telescope objecti- ve lens is described.MTF determination of zero viewing field of λ_D,λ_C,λ_,λ_W are ma- de on maximum image plane(D=0.824mm)of corresponding MTF when focal length s 500 mm,wavelength λ_D,and axial spatial frequency is 35.4 L/mm.The correspond- ing MTF of characteristic spatial frequency 12 L/mm and 35.4 L/mm are served as thn image quality evaluation standard. | | 本文叙述了自制大型变焦距电视望远物镜的象质评价。λ_A、λ_C、λ_F、λ_W 的零视场的 MTF 测量,是在焦距为500毫米、波长λ_D、轴上空间频率为35.4L/mm 时所对应的 MT 值最大的象面位置(D=0.824毫米)上进行的。把特征空间频率12L/mm 和35.4/Lmm 所对应 F 的 MTF 值作为象质译价的标准。 | | 文摘来源 | | The principles of the measurement of apparent temperature are discussed. The measured results of apparent temperature of typical terrestrial materials and experimental results of radiometric imaging at 8.63 mm wavelength are reported. The effects of polarization, surface roughness and physical temperature on surface apparent temperature are investigated. It is shown that the contrast of the radiometric images obtained is sufficient for the identification of the objects of interest. | | 本文论述了视在温度测量原理,给出了8.63毫米波长下某些地物视在温度的测量结果和辐射成象的试验结果;研究了极化、表面粗糙度和物理温度对表面视在温度的影响。结果表明,获得的辐射图象的对比度足以识别出所研究的目标。 | | 文摘来源 | | Measurement results of apparent sky temperature over a period of a year at 35 GC are reported. The temperatures were measured at different zenithal angles under various meteorological conditions and compared with calculated results. Actual calculation of the temperatures for a serene sky is studied. The instrumentation is described and the results are discussed. | | 在八毫米波长下,对微波天空温度进行了为期一年的测量,获得了各种气象条件下不同天顶角的微波天空温度。提出了一个晴空微波天空温度的工程计算公式。文中还对实验方法和实验结果进行了理论分析。 | | 文摘来源 | |   | | << 更多相关文摘 |
