infrared filter

this paper adopts surveillance camera and infrared filter to acquire double band image.

采用工业监控摄像机和红外滤光片实现双波段图像的采集。

attach the infrared filter and focus on the subject. read the indicated distance off the lens barrel.

按上红外线滤光片，对拍摄景物对焦，请读出镜头筒指示的距离。

using an infrared filter has heightened this effect further, in colour the image would probably not have been so appealing .

利用红外过滤器提高了这一效应，进一步彩色图像可能不会如此吸引人。

design and application of a new-type tunable infrared filter

一种新型可调谐红外滤光片的设计和应用

in most cases, an infrared filter is used which lets the infrared light to pass through to the camera.

在许多情形下，会用到红外线滤镜，这可以将红外光传入到相机。

structure, bandwidth estimation and adjustment of medium bandpass infrared filter

红外中带滤光片的结构、带宽估算及调整

in the detector the infrared filter is the core part of the device.

其中近红外滤光片为该装置的核心部件。

study of narrow band photonic crystal infrared filter

窄线宽光子晶体红外光滤波器研究

with the current technique, both the etching and the depositing methods can be used to fabricate the integrated infrared filter.

在现有工艺条件下，采取刻蚀法或镀膜法均能实现红外集成滤光片的制作。
