processing method on the same substrate of the detector is called the single-chip IRFPA infrared processing method, while the infrared detector (IRD) is prepared on different substrates respectively, then, the hybrid IRFPA is formed by reinstallation and interconnection of the primary column. Infrared Detectors (IRD) have different types, such as photovoltaic type (PV) Antimony indium IRD, light-conducting type (PC), hgcadmium, PBS, PbSe, phsnteird, metal silide (pd2si, ptsi, irsi), two-step sb
Focal Length: the distance from a point in focus of a parallel light that is reflected by the lens to the center of the plane in which the lens is located. The length of focal length determines the lens angle of view, which is the same as the distance from the camera to the subject,Field of viewLarge, shooting range (photo field)WIDE; small angle of view, small Shooting Range

I recently saw some discussions about focal lengths in the forum, so I want to talk about the focal lengths. I hope it will be good for you. If any, please note.
The focal length of the camera lens is a very important indicator of the lens. The length of the lens focal length determines the size of the object to be i

As we all know, the current target detection (objece detection) algorithm is mainly divided into two main categories: Two-stage detector and One-stage detector. Two-stage detector mainly includes rcnn, FAST-RCNN, faster-rcnn and RFCN, one-stage detector and SSD, the former is high precision but slow detection speed, the latter is low precision but fast.

Link Management in Rational Focal point
The integration of the rational solution of IBM Rational Focal Point with collaborative lifecycle Management (CLM) applications is based on the linked Data technology. In other words, links created between rational Focal point and CLM applications, such as rational Requirements Composer and Rational Team concert, are an im
This article mainly introduces how to solve the problem that the input box at the upper layer of modal cannot obtain the focus in the Bootstrap pop-up box, which has some reference value, if you are interested, you can refer to the Bootstrap pop-up box and the input box on the modal layer cannot obtain the focus. The details are as follows:
1. In the Bootstrap framework, the modal pop-up box currently only supports one layer.
That is, you cannot use the modal pop-up box in the current pop-up bo
