测量了离体人脑组织切片的光学特性。实验用积分球进行，覆盖400至1100 nm的波长范围。研究了正常脑组织（白色和灰质）和肿瘤组织（恶性胶质瘤和黑色素瘤）。从实验数据的Kubelka-Munk吸收和散射系数确定。从这些数据中，我们计算了传输吸收和散射系数，通过使用扩散近似。血液和水似乎是主要的发色团。在上述波长范围内，吸收系数的变化超过两个数量级。散射系数向短波长方向缓慢增加。
The in vitro optical properties of slices of human brain tissue were measured. The experiments were performed with an integrating sphere and covered the wavelength range from 400 to 1100 nm. Both normal brain tissue (white and grey matter) and tumour tissue (a malignant glioma and a melanotic melanoma) were investigated. From the experimental data the Kubelka-Munk absorption and scattering coefficients were determined. From these data we calculated the transport absorption and scattering coefficients by using the diffusion approximation. Blood and water appeared to be the dominant chromophores. In the wavelength range mentioned, the absorption coefficients varied over more than two orders of magnitude. The scattering coefficients increased slowly towards the shorter wavelengths.
