An objective method for color vision deficiencies measurement based on visual evoked potential

Normal color perception depends on the absorption of photons by the three classes of cone photoreceptor in the retina. As the peak sensitivities of the three cones, it is convenient to refer to the three types of cone as S-cone, M-cone, and L-cone respectively[1]. But any malfunction of the cones can lead to abnormal color appreciations. They are called color vision deficiencies. Many forms of them are congenital in origin, although it can be acquired as a result of eye disease, or as a side…     

积分球理论的级数收敛法

本文从积分球内分光的多次反射原理出发,用级数收敛法得到了用积分球进行光度色度测量时替代法和比较法二类方法所存在的非线性误差,并给出误差校正分式,最后提出积分球参数的设计原则。
