Photoelectric detection device with positioning function

Abstract

The invention discloses a photoelectric detection device with positioning function, which comprises a device main body and a light-shielding cover. The right end of the device main body is provided with a photomultiplier tube, the left end of the photomultiplier tube is fixedly connected in the device main body, and the left end of the device main body is provided with a fixed Seat, the right side of the fixed seat is embedded in the main body of the device, the lower end of the fixed seat is provided with a vent cap, and the top of the vent cap is fixedly connected in the fixed seat. This kind of photoelectric detection device with positioning function prevents heat flow from passing through other components, which suppresses thermionic emission from the photoelectric surface. In this state, the light to be detected transmitted through the light incident window of the optical filter passes through The aperture diaphragm of the laser distance measuring device is incident on the photoelectric surface of the laser distance measuring device. After the aperture diaphragm of the object is determined, the device is not restricted by the size of the object, and can detect any object or optical The convenient operation of telemetry and remote control by signal improves the user experience and expands the scope of use.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection devices, in particular to a photoelectric detection device with a positioning function. Background technique [0002] Photoelectric detection technology is a new detection technology produced by the combination of optics and electronics. It mainly uses electronic technology to detect optical signals, and further transmits, stores, controls, calculates and displays. In principle, photoelectric detection technology can Detect all non-electricity that can affect the amount of light and light characteristics. It can convert the non-electricity information to be detected into optical information that is easy to accept through the optical system, and then use photodetectors to convert the optical information into electricity, and further amplify through the circuit. Processing to achieve the purpose of electrical signal output, and then use electronics, information theory, computer and p...

Problems solved by technology

[0003] However, when the existing photoelectric detection device is in use, it is impossible to accurately locate the measurement object. As the object shifts, it will cause measurement deviation and affect the measurement effect. In addition, the existing photoelectric detection device has low detection accuracy and slow speed, so it cannot Telemetry and remote control affect the user experience, and there are requirements for the shape and size of the detected object, so the scope of use is narrow
