    Abstract: Varias modalidades incluyen sistemas y métodos para proporcionar ganancia variable seleccionable a señales en mediciones utilizando la radiación incidente. La ganancia variable seleccionable se puede usar para normalizar señales moduladas en mediciones utilizando la radiación incidente. La ganancia variable seleccionable se puede lograr utilizando varias técnicas diferentes o varias combinaciones de estas técnicas. Estas técnicas pueden incluir modular un modulador que tiene elementos moduladores en el cual al menos un elemento modulados actúa en la radiación incidente de manera diferente del otro elemento modulador del modulador, modulando el uso de componentes electrónicos en la circuitería electrónica de un detector, modulando una fuente de radiación o combinación de ésta. Se describen aparatos, sistemas y métodos adicionales.

    Abstract: The apparatus for measuring changes in parameters at an object (2), which is permeable to light, has a light source (1) and an optical line sensor (3) on the opposite side of the object to register the intensity of the light passing through at positions, and a computer (4) which gives the distribution of the light intensities to be compared with at least one reference distribution. Preferred Features: The line sensor is a charge coupled device (CCD). The lamp is a point light source to deliver parallel light. A reference distribution is stored in the computer memory, taken without any influences for the light passing through a dummy object to a line sensor, or with a known change in the light refraction or light scatter characteristic against the dummy object. The stored reference distribution takes into account known changes in the color filter characteristics. At least one reference distribution is a mathematical model, giving values through a curve analysis. The line sensor has separate color sensors, and especially red and green and blue, to measure the coloration of the object. The comparison at the computer is a correlation where the parameter change at the measured object against a dummy object is taken as the strength of the correlation with the reference distribution for the parameter in question. The object is a medical hose tube (6), carrying a flow of a liquid medium (5) such as blood. The object can also be a divided container, with two chambers symmetrical to the dividing wall, each filled with a different liquid medium. The dividing wall lies on the symmetrical plane of the light source and the line sensor. The measured parameter changes are stored according to time, for the stored values additionally to give a dynamic change in the parameter of the liquid medium. The measurement of parameter changes, against a dummy object, is simultaneous for both chambers of a divided container. The light intensity distribution measured in one chamber acts as a reference distribution for the evaluation of the light intensity distribution measured at the other chamber. The same principle applies to a container with more than one dividing wall giving three chambers or more.
