Abstract
SENSOR INFRAVERMELHO DE PRESENçA DE ALTA SENSIBILIDADE, notadamente de um sensor IVP cuja lente (1) de Fresnel de geometria específica é dotada de filtro óptico embutido capaz de realizar o discernimento entre intrusos humanos e pequenos animais que eventualmente invadam a área monitorada pelo referido sensor (5) em que o discernimento ou identificação é efetivado no nível da óptica e não no da eletrónica como nos sensores convencionais, em que a obtenção de tais lentes (1) é realizada preferencialmente por processos de injeção termoplástica cujos moldes são confeccionados por ablação a laser, não agregando custo ao processo de obtenção da lente.HIGH SENSITIVITY INFRARED SENSOR, notably an IVP sensor whose specific geometry Fresnel lens (1) has a built-in optical filter capable of discerning between human intruders and small animals that eventually invade the area monitored by that sensor ( 5) wherein the discernment or identification is effected at the optical level rather than the electronics level as with conventional sensors, wherein obtaining such lenses (1) is preferably performed by thermoplastic injection processes whose molds are made by laser ablation. , adding no cost to the lens making process.
