Abstract (en)

[origin: WO2018077573A1] The invention relates to a method for operating a microspectrometer (102), wherein the method involves the following steps: irradiating a measurement object (130) to be measured with a first spectral intensity distribution (120) with first pulse characteristics (118) and with a second spectral intensity distribution (124) with second pulse characteristics (122) using a modulatable emitter device (106) of the microspectrometer (102); allowing a first wavelength range (134) associated with the first spectral intensity distribution (120) and a second wavelength range (136) associated with the second spectral intensity distribution (124) from a spectral reflection intensity distribution (132) re-emitted from the measurement object (130) to pass through using an adjustable filter device (108) of the microspectrometer (102); mapping a radiation intensity of the first wavelength range (134) and the second wavelength range (136) in a detector signal (138) using a detector device (110) of the microspectrometer (102); and demodulating the detector signal (138) using the first pulse characteristics (118) and the second pulse characteristics (122), in order to obtain 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).
