The continuous telecentric zoom lens for a digital light processor (DLP) projector with prisms is presented.
介绍了含有棱镜系统的数字光处理器(DLP)投影仪连续变焦距远心镜头的设计。
Nevertheless, VST has successfully elevated the industry benchmark by adding many new models to the lineup for high mega-pixel telecentric lenses in a relatively short period of time.
Furthermore, the selection of the double telecentric optical system ensures the correction of the trapezoidal distortion introduced by the tilt object surface.
选择双远心光学结构,便于对倾斜物面所产生的梯形畸变进行矫正。
The relation between aberrations of the telecentric projection objective and the pitch CCD is discussed. The criterion of correcting aberrations in the telecentric projection objective is also given.
讨论远心投影物镜像差和CCD节距的关系,给出远心投影物镜校正像差的依据。
Because maximum field of view in telecentric systems directly relates to the lens aperture closest to the object, larger front lenses are necessary for larger fields of view.
The optical system only consists of three germanium lenses with a 「negative-positive-positive」 reversed telephoto telecentric structure in the image space.
采用「负-正-正」型式的反远距像方远心光路镜头结构,仅有三块非球面锗透镜构成。
Due to weight and center of gravity concerns, the 0.125x telecentric lens requires a mounting clamp and 0.08x telecentric lens includes mounting clamp (removable).
To study the structure of telecentric beam path for zoom lens system, the axial displacement equation for the stop was deduced, which keep the system telecentric in all zoom position.
This paper uses an object telecentric beam path in a diameter measurement system, designs a data acquisition circuit , and presents a accuracy measure method with polynomial interpolation.
