Design of Programmable Near Infrared Cold Light Source
In the near infrared spectroscopy, detector of Charge-coupled Device requires very high stability for light source. We design the cold light source in the measurement of near infrared spectroscopy. Cold light source consists of high-power op amp OPA549 high current constant current source and proportion integral differential (PID) control algorithm. As is shown in the experimental results, the method is better, the overshoot is very small, the stability is excellent in the process of soft-start. While light intensity was able to meet the requirements of nearinfrared instruments to measure.
