Abstract: Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.

Abstract: Disclosed is a method for identifying and eliminating ammonium salt deposition characteristics in a pipe of a hydrogenation air cooler. A multiphase flow medium enters an inlet pipe box of a hydrogenation air cooler; cross sections and temperature transmitters are arranged on a pipe bundle of the air cooler in the axial direction; a temperature signal value is monitored and transmitted to a single-chip microcomputer for analysis; an infrared thermal imager performs photographing, and transmits data to determine that an ammonium salt deposition risk is present under this working condition; a monitored temperature value is calculated, an ammonium salt deposition risk identification model is established, and ammonium salt deposits are peeled off from the inner wall of the pipe bundle of the air cooler by means of vibration of the pipe bundle caused by the intermittent frequent switching-on/switching-off of an electromagnet and a magnetic block, and ultrasonic signals.
