Abstract
A device is described for measuring changes in parameters in transparent objects, in particular for medical applications. For universal use in various applications, the device includes a light source, an optical line sensor which detects the intensity of the light of the light source passing through the object as a function of location in at least one extension direction of the object, and a computer unit which compares the distribution of the light intensities detected by the optical line sensor as a function of location with at least one predetermined reference distribution. According to another embodiment, the light source supplies approximately parallel light, and the computer unit shapes the first derivation according to location of the distribution of the light intensities detected by the optical line sensor. The device is designed so that the different light sources can be easily replaced or combined.
