Stabilization of parameters of optoelectronic devices on semiconductor emitters

The current state of using LEDs for gas analysis, environmental monitoring, hygrometry, medical diagnostics, and communication systems is analyzed. Existing methods for ensuring the stability of LED parameters, their significance, and application in automatic control devices are considered, along with the advantages and disadvantages of building multichannel optical schemes (thermostabilization, thermocompensation, thermostating). It is identified that little attention has been paid to ensuring the stabilization of LED radiation fluxes used in optoelectronic devices for automatic control. A method for stabilizing parameters (radiation power, radiation intensity, radiation flux, peak spectrum, direct current, direct voltage) of LEDs with optical negative feedback has been developed to enhance the measurement accuracy and reliability of optoelectronic devices on semiconductor emitters. A structural diagram of optoelectronic devices on semiconductor emitters has been developed to ensure its temporal stability.
