Embodiment Construction

[0142] The individual components a) to e) of the sensor according to the invention will be described below:

[0143] a) One or more light sources (LQ), preferably two light sources (LQ)(TM / VS) and (LQ)(REM)

[0144] Physical function:

[0145] In principle, each individual measurement originates from a light source (LQ) that supplies light in the desired wavelength range with the necessary intensity, constancy and lifetime.

[0146] Many different principles can be envisaged as light source (LQ), ranging from lamps with incandescent filaments, gas discharge lamps, to LEDs. The advantages of LEDs are the possibility to keep the intensity constant with constant current operation, and the fact that a mechanical shutter can be avoided (current off = light off). The use of lasers is also possible.

[0147] Therefore, the light source (LQ) is selected (in the case of using several light sources, preferably independently of each other) from the group consisting of: LEDs, preferabl...
