摘要
本文在全面比较了各类光电器件相对光谱灵敏度S(λ)_r的基础上,设计了用热释电探测器作参考基准,用积分球作单色光辐射接收系统的S(λ)_r测量系统.由于设计上的优点,这一系统大大减少了入射辐射的偏振性,不均匀性,探测器的温漂和杂散辐射等因素带来的误差.
In this paper, bhe relative gpectral sensitivity distributions [S(λ)r] of photoelectric detectors are classified and compared. On the basis of above considerations, a new method for measuring S(λ)r using the pyroeleotrio detecbor as the reference and the integrating sphere as the monoohromatio radiation receiver has been suggested and designed. Because of the advantages of system structure, guch error factors as polarization and nonuniformity of incident radiation, temperature drift of detectors and stray radiation are decreased significantly.
