    • A system and method employing optical disk drives for quantitative analysis of chemical and biochemical parameters, in which sensor materials disposed on an optical disk are responsive to physical, chemical, biochemical, and other parameters in the environment. The light interacts with the sensor materials when the light propagates through the sensor material, reflects off the optical media's reflective layer, and propagates back through the sensor region. The interacted light is captured by a photodetector, which outputs a response analog signal, for example, an analog voltage signal, which is indicative of a condition of the environment to which the sensor materials have been exposed. The system includes software algorithms which cause the laser source and optical detector to move to a specified location or logical block address of the disk, measure the optical signal during disk rotation, display a map of the sensor material response, and reduce the noise level in the measured signal.
    • 一种使用光盘驱动器进行化学和生物化学参数的定量分析的系统和方法,其中设置在光盘上的传感器材料响应于环境中的物理,化学,生物化学和其它参数。 当光传播通过传感器材料时,光与传感器材料相互作用,从光学介质的反射层反射并传播回传感器区域。 相互作用的光被光电检测器捕获,光电检测器输出响应模拟信号,例如模拟电压信号,其表示传感器材料暴露于的环境的状况。 该系统包括使激光源和光学检测器移动到盘的指定位置或逻辑块地址的软件算法,在盘旋转期间测量光信号,显示传感器材料响应的映射,并降低噪声水平 测量信号。
