OPTOELECTRONIC SENSOR, OPTOELECTRONIC COMPONENT COMPRISING AN OPTOELECTRONIC SENSOR AND METHOD FOR OPERATING AN OPTOELECTRONIC SENSOR

摘要

Disclosed is an optoelectronic sensor (5) for detecting a change in the performance and/or the wavelength of a light source (10) in at least one wavelength range (λ_1,min, λ_1,max), said sensor comprising a first photodetector (1) and a second photodetector (2), the first photodetector (1) having a spectral sensitivity S₁(λ) and the second photodetector (2) having a spectral sensitivity S₂(λ). The spectral sensitivities differ from one another and a quotient S₁(λ)/S₂(λ) of the spectral sensitivities in the at least one wavelength range (λ_1,min, λ_1,max) increases monotonically or decreases monotonically. Also disclosed are an optoelectronic component (12) comprising the optoelectronic sensor (5) and a method for operating the optoelectronic sensor (5).
