ABSTRACT:
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.
