利用泵浦探测方法研究了细菌视紫红质薄膜的光致各向异性。用二极管泵浦的二次谐波激光作为抽运光，用波长分别为442、532、655 nm的三个波长作为探测光。没有泵浦光束，探测光就不能将分析器传输到检测器。然而，由于光致各向异性，当泵浦光束存在时，探测光的一部分被检测到。基于这一特性，我们展示了一种全彩色全光显示器。
Photoinduced anisotropy in a bacteriorhodopsin film using the pump-probe method was investigated. A diode-pumped second-harmonic YAG laser was used as the pump beam, and three wavelengths, at lambda = 442, 532, 655 nm, from different lasers were used as probe beams. Without the pump beam, the probe light cannot transmit the analyzer to the detector. However, because of photoinduced anisotropy, a portion of the probe light is detected when the pump beam is present. Based on this property, we demonstrate a full-color all-optical display.
