Intelligent video microscope with continuous zoom: 1. The continuous zoom video microscope's mechanism of operation
The binocular observation type stereo microscope is where the continuous zoom video microscope (hence referred to as the video microscope) begins. Its optical system is primarily made up of three components: an eyepiece, an additional front objective lens, and a continuous zoom objective lens, which is the major part of a video microscope and falls under the category of low magnification objectives. The target item is photographed on the CCD's (or CMOS's) photosensitive surface through theoptical system, the image sensor transforms the light signal into an electrical signal (video signal), and the TV system then displays the image of the item on the CRT or LCD screen. The Guidian Institute of Electro-Optical Mechatronics and Wuzhou Aote Optoelectronics Instrument Co., Ltd. created the DT-10 monocular continuous zoom video microscope. With a 1 eyepiece and no front objective lens, the zoom ratio M=1:6.3 offers a continuous zoom range of 0.7 to 4.5 times. The microscopic image is seen on the CLD after being connected to the 1/3inch CCD through the C interface. Additionally, the optical system uses an annular LED array for exterior illumination or coaxial LED lighting with adjustable light intensity.
1.2 Video microscope automation and intelligent transformation (1) The issue is brought up. Online automatic inspection of industrial manufacturing processes frequently uses machine vision. The continuous zoom video microscope's "manual adjustment + video observation" option cannot fulfill the criteria for online automatic inspection.
(2) The overall design plan. The fundamental idea behind an intelligent continuous zoom video microscope is to use embedded technology in the continuous zoom system in place of a conventional computer to autonomously regulate the activity of the microscope. Its straightforward and useful technology makes it possible to replace the video microscope with manual zoom and computer zoom while at the same time easily realizing the automatic zoom, focus, and detection capabilities. It must have two features: automatic focusing and electrically controlled brightness.regulated zoom. 1) It is clear from the literature that the concept behind the automatic focusing technique is that the stepping motor is driven and implemented after the microscopic picture acquired by the optical system is identified by "CCD+PC". 2) In order to achieve the goal of continuous zooming of the optical system, the electronically controlled zoom scheme can be used in place of the manual rotation of various angles on the zoom handwheel. 3) The overall structure of the text is created using the ideas mentioned previously.
