El repte/The challenge
Collimated transmittance, that is, the light crossing through a transparent or semitransparent body, is difficult to measure accurately. Systems to measure it involve integrating spheres ad similar photometric arrangements, which are oftwentimes used in order to measure optical parameters of the sensor, including, among others, refractive index. In this system, a very cheap laser sensor based in Optical Feedback Interferometry is used to measure it just by pointing the laser onto . The third order moment of the frequency components of the signal yields a detailed measure of the transmittance of the body in a fast, straightforward and reliable manner.
La tecnologia/The technology
Optical Feedback Interferometry is a very powerful experimental technique where a laser diode is used simultaneously as source, interference media, and sensor. The light backrreflected from some target gets back in the cavity, and the interference which appears may be recorded using the monitor photodiode available in those laser diodes. By pointing the laser to a semitransparent body, like glass, or a tissue phantom, it is possible to estimate reliably the collimated transmittance of the target from a statistical analysis applied onto the signal being recorded.
