| 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 (lambda1 ,min, lambda1,max), said sensor comprising a first photodetector (1) and a second photodetector (2), the first photodetector (1) having a spectral sensitivity S1(lambda) and the second photodetector (2) having a spectral sensitivity S2(lambda). The spectral sensitivities differ from one another and a quotient S1(lambda)/S2(lambda) of the spectral sensitivities in the at least one wavelength range (lambda1,min, lambda1,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). |
