The FPC flexible board endoscope camera is an imaging device that integrates a flexible printed circuit. It is usually composed of a lens, an image sensor, a flexible circuit board and related electronic components. The following is a detailed introduction:
Structural features
Lens: Usually a micro optical lens is used, which has high resolution and good optical performance, and can obtain clear images in a small space. The focal length and field of view of the lens can be designed and adjusted according to different application requirements.
Image sensor: It is the core component of the camera and is responsible for converting optical images into electrical signals. Common image sensors CMOS, CMOS sensors have the advantages of small size, low power consumption and low cost and are widely used in endoscope camera products.
Flexible circuit board: Used to connect lenses, image sensors and other electronic components, with good flexibility and bendability, can adapt to the bending and twisting of endoscopes in the human body or industrial equipment. Signal transmission lines, power lines and control lines are also integrated on the flexible circuit board.
Working principle
Connect the endoscope camera to a computer or mobile phone via a USB cable, the endoscope camera light source illuminates the object being observed, and the light is focused on the image sensor through the lens.
The image sensor converts the optical signal into an electrical signal, and then transmits the electrical signal to an external computer monitor or mobile phone through a flexible circuit board. After processing and display, the user can see the image of the observed object.
Application field
Industrial field: used to inspect the internal structure and defects of industrial equipment, pipelines, mechanical parts, etc., such as the inspection of aircraft engine blades, the inspection of automobile engine cylinders, the corrosion and blockage inside pipelines, etc. The flexible board endoscope camera can be inserted into the equipment through a narrow opening or gap to obtain a clear image, providing a basis for the maintenance and repair of the equipment.
Medical field: widely used in medical endoscopes such as gastroenteroscopes, bronchoscopes, and laparoscopes. Doctors can use flexible board endoscope cameras to observe the pathological conditions of internal organs and tissues of the human body and diagnose and treat diseases. For example, in gastroenteroscopes, the camera can be inserted into the digestive tract through the mouth or anus to help doctors find lesions such as gastric ulcers, polyps, and tumors.
Advantages
High flexibility: It can freely shuttle in curved and narrow spaces, and can reach parts that traditional rigid cameras cannot reach, greatly expanding the application range of endoscopes.
Good image quality: The use of advanced optical lens and image sensor technology can provide high-resolution and clear images, which helps doctors or technicians observe and judge more accurately.
Miniaturization: The overall structure is compact and small, which is easy to install at the front end of the endoscope without adding too much burden and taking up too much space.
Limitations
High cost: Due to its high technical content and complex manufacturing process, the cost of flexible board endoscope cameras is relatively high, which to a certain extent limits its wide application.
Limited durability: Despite special design and treatment, flexible circuit boards may still suffer from fatigue and damage during frequent bending and twisting, affecting the service life of the camera.
Image quality is affected by the environment: In some special environments, such as high temperature, high humidity, strong magnetic field, etc., the image quality of the camera may be affected, and even the camera may not work properly.
