Embodiment Construction
[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0047] refer to figure 1 As shown, the present invention discloses a reflective imaging film, which includes a transparent spacer layer, a microfocusing unit array layer, a reflective layer and a micrographic layer.
[0048]The transparent spacer layer 12 includes a first surface and a second surface disposed opposite to each other. The micro-focusing unit array layer 13 is provided on the first surface, and the micro-focusing unit array layer 13 includes at least three micro-focusing units. The reflective layer 14 covers the outer surface of the micro-focusing unit array layer 13, and the micro-focusing unit array layer 13 and the reflective layer 14 constitute a reflective micro-foc...

Abstract
The invention relates to a reflective imaging film, comprising: a transparent spacer layer, the transparent spacer layer includes a first surface and a second surface oppositely arranged; a micro-focus element array layer, the micro-focus element array layer is arranged on the first surface, and the micro-focus element array layer The focusing element array layer includes at least three micro-focusing units; the reflective layer, the reflective layer covers the outer surface of the micro-focusing element array layer, and the micro-focusing element array layer and the reflective layer constitute a reflective micro-focusing layer; the micro-graphic layer is arranged on On the second surface, the micro-text layer includes at least three micro-text units, each micro-text unit is different, and the micro-text layer is obtained by cutting the whole part of the virtual stereoscopic image through projection imaging of the reflective micro-focusing layer; wherein , a stereoscopic image with continuous parallax and occlusion relationship can be observed through the transparent spacer layer. Through the combined effect of the reflective micro-focusing layer and the micro-graphic layer, it provides a true stereoscopic image with a full field of view and dense viewpoints.
Description
technical field [0001] The invention relates to the technical field of optical anti-counterfeiting, in particular to a reflective imaging film. Background technique [0002] In recent years, counterfeit and shoddy goods have been flooded in my country's market, such as food, various brand-name wines, beverages, cigarettes, medicines, health products, cosmetics, washing products, clothing, footwear, film, medical equipment, steel, cement, chemical raw materials, Chemical fertilizers, pesticides, seeds, auto parts, TV sets, etc.; from the perspective of social and public security, there are also a large number of counterfeit banknotes, stamps, various securities, resident ID cards, household registers, graduation certificates, official seals, etc. There are so many types of fake and shoddy goods, and the distribution range is wide, and the serious consequences are really shocking. In particular, counterfeit banknotes, stamps and other securities are the most serious harm to so...
