Method and control device for operating a microspectrometer and microspectrometer system

摘要

The invention relates to a method for operating a microspectrometer (102), the method comprising a step of irradiating a measured object (130) to be measured with a first spectral intensity distribution (120) having a first pulse characteristic (118) and at least one second spectral intensity distribution (124 ) having a second pulse characteristic (122) using a modulatable emitter device (106) of the microspectrometer (102), a step of transmitting one of the first spectral intensity distribution (120) associated first wavelength range (134) and one of the second spectral intensity distribution (124) second wavelength range (136) from a spectral reflectance intensity distribution (132) re-emitted by the measurement object (130) using a tunable filter device (108) of the microspectrometer (102), a step of imaging a radiation intensity of the first wavelength range (134 ) and the second wavelength range (136) in a detector signal (138) using detector means (110) of the microspectrometer (102) and demodulating the detector signal (138) using the first pulse characteristic (118) and the second pulse characteristic (122) a first intensity value (140) associated with the first wavelength range (134) and a second intensity value (142) associated with the second wavelength range (136).
