Com o desenvolvimento da ciência e tecnologia e a abertura de políticas nacionais, a caça legal tornou-se gradualmente um novo tipo de entretenimento ao ar livre. Existem muitos fãs militares e entusiastas de atividades ao ar livre que têm uma demanda crescente por termovisor e dispositivos de visão noturna. Ao mesmo tempo, muitos internautas com forte sede de conhecimento estão perguntando: O que exatamente são termovisor e dispositivos de visão noturna?


Today, preste atenção, nossa palestra de conhecimento está aberta!


In , termovisor e dispositivos de visão noturna são equipamentos de alta tecnologia que podem fornecer imagens de alta definição no escuro e podem facilmente obter imagens de alvos claros em um ambiente completamente escuro.

At atualmente, eles têm sido amplamente utilizados em segurança militar, tecnologia industrial, direção assistida por automóveis, inspeção de prevenção de epidemias, prevenção de incêndios florestais, caça ao ar livre e remédios.


So qual é a diferença entre termovisor e dispositivos de visão noturna? Continue lendo:


Thermal imageadores são infravermelhos passivos, que dependem da recepção de energia infravermelha (temperatura / energia térmica) emitida pelo próprio objeto e, em seguida, apresenta-o através do display após o recebimento e processamento.


The imagem resultante tem vários modos de exibição. Por exemplo, os produtos de imagem térmica da PARD Technology têm cinco modos de imagem: pseudo-cor vermelha em brasa, branco-quente, preto-quente, pseudo-cor vermelho-ferro e céu. A imagem térmica não depende de si mesma para emitir raios infravermelhos, mas apenas recebe raios infravermelhos do mundo exterior.


Night dispositivos de visão estão ativos, o que significa que a luz deve ser refletida nos objetos e o dispositivo de visão noturna recebe a imagem. Os dispositivos de visão noturna na faixa civil são geralmente dispositivos digitais de visão noturna, que podem ser usados dia e noite. Sob boas condições de iluminação durante o dia, o efeito de imagem é mais claro e alguns produtos podem apresentar imagens coloridas.


At noite, sob as condições de fontes de luz externas ou luzes de autopreenchimento, a maioria das imagens é preta e branca. Em um ambiente completamente escuro, os produtos de visão noturna digital da PARD Technology podem fornecer imagens de visão noturna de alta definição dentro de um alcance infravermelho de 350 m.


Thermal Imagers And Night Vision Devices


So do ponto de vista das necessidades de caça ao ar livre, como escolher dispositivos de imagem térmica e dispositivos de visão noturna? O seguinte fornecerá uma resposta simples para amigos com necessidades básicas:


In ambiente de caça noturna, óculos de visão noturna são usados para observar o alvo. A distância que pode ser observada é relativamente próxima e o efeito de imagem é mais próximo da aparência real do próprio alvo observado, mas existem certas limitações, ou seja, o alvo é facilmente confundido quando se mistura com o ambiente e não é fácil de encontrar.

However, sua imagem é mais realista e a aparência real e o contorno do objeto podem ser observados a uma certa distância e seu preço é relativamente barato, então amigos com um orçamento baixo podem escolher óculos de visão noturna.


In comparação, a distância de detecção de termovisores é maior e usa o princípio da imagem térmica, usando a diferença de temperatura para distinguir entre fontes de calor e interferências ambientais circundantes, para que seja mais fácil encontrar a existência do alvo. No entanto, seu preço é geralmente mais caro e o limite de entrada é mais alto.


Thermal Imagers And Night Vision Devices


Finally, para resumir, não há diferença entre os dois produtos, depende de suas necessidades e orçamento. Aqui, também desejo que cada espectador possa encontrar um produto de visão noturna de imagem térmica que se adapte a ele e que ele goste.
