[0027] Example

[0028] The technical idea of ​​the present invention is: the essence of optical camouflage is to simulate the spectral reflection characteristics of the background, and the most important and most critical is to simulate the spectral reflection characteristics of green vegetation, and generally artificial green camouflage materials and green vegetation have different spectral reflections curve( figure 1 and figure 2 ). figure 1 and figure 2 The spectral curves of typical green vegetation and general artificial green materials are given, the abscissa is the wavelength (unit nm), and the ordinate is the spectral reflectance (%). It can be seen from the figure: in the visible light band (380-760nm), due to the action of chlorophyll, plant leaves have a reflection peak around 550nm, which makes them mainly green; in the near-infrared band (760-1100nm), due to the chlorophyll cell structure , which makes it highly reflective in the near-infrared band. It i...

Abstract

The invention discloses an inspection mirror capable of visually identifying green camouflage and a preparation method thereof. The inspection mirror can identify an artificial green material with thesame color as green vegetation and different spectrums from the green vegetation. According to the invention, blue filter glass QB3 is used as a substrate material, and two surfaces of the blue filter glass QB3 are plated with long-wave-pass cut-off filter films; the long-wave-pass cut-off filter film is formed by alternately coating a high-refractive-index coating material and a low-refractive-index coating material for multiple times. The filter lens of the inspection mirror has very obvious selectivity in visible light and near-infrared regions, and a large amount of red light and near-infrared light with the wavelength of 680 nm or above can penetrate through the filter lens; a small amount of blue-green light with the wavelength of 470-520 nm is transmitted, and a tiny transmission peak value exists near 500 nm or 510 nm; and in other wave bands, little light can penetrate, so the camouflage implementation effect can be visually identified and judged by any engineering camouflagepersonnel.

Description

technical field [0001] The invention relates to an inspection mirror capable of forming a specific transmission spectrum for identifying green camouflage and a film-making method thereof. The present invention is a very convenient device that can visually identify optical camouflage and its camouflage degree. Furthermore, the present invention can identify artificial green materials with the same color and different spectrum from green vegetation. Background technique [0002] Conventional detection methods for green camouflage materials mainly use visible / near-infrared spectrophotometers to test the spectral reflectance characteristic curves of materials in indoor environments, but professionals are required to test and analyze the result data; Field transient spectrometers test the spectral reflectance properties of materials. The test results are greatly affected by solar radiation, test angle, distance, etc. Professionals are also required to operate the test and analyze...
