The invention relates to an ear-nose endoscopic examination and imaging system provided with a Wood lamp and a working method of the ear-nose endoscopic examination and imaging system. The ear-nose endoscopic examination and imaging system comprises a light source device and an operation and lens device, the light source device comprises a reflective concave mirror, a xenon lamp, a first dimming lens, a second dimming lens, a rotary glass aperture, a rotary nickel hydride filter aperture and a light guide cable; the reflective concave mirror, the xenon lamp, the rotary glass aperture, the first dimming lens, the rotary nickel hydride filter aperture and the second dimming lens are arranged in sequence; the second dimming lens is arranged opposite to one end part of the light guide cable; the operation and lens device is connected with the light source device through a light guide cable. Compared with the prior art, the wood lamp and the ear-nose endoscope are combined, and the defect that the treatment effect cannot be accurately evaluated due to ear-nose fungal infection and specific bacterial infection is effectively overcome.

This invention belongs to the field of materials technology and relates to a method for preparing and applying nickel hydrogen phosphate electrochromic nanomaterials. It overcomes the technical problems of existing nickel-based electrochromic materials, such as low transmittance, small optical modulation range, and difficulty in large-size fabrication after film deposition on transparent conductive substrates. The method for preparing the described nickel hydrogen phosphate electrochromic film employs room-temperature electrodeposition technology. The prepared nickel hydrogen phosphate electrochromic material exhibits small, uniform nanoparticle size and allows for the construction of large-size in-situ films (10 × 10 cm). 2 The characteristics of this method make it suitable for constructing high-performance electrochromic films. The prepared films have the characteristics of high transmittance in the faded state, wide spectral modulation range, and high coloring efficiency. Moreover, the preparation process is low-cost and efficient, and can be mass-produced, making it easy to realize industrial production. It has broad application prospects in the fields of electrochromism, flexible wearables, and smart displays.
