Problems solved by technology

[0004] At present, laser displacement sensors have been used in many fields, but they have high requirements on the application environment. High temperature, dusty environment, and reflected light from flat mirrors will affect the regulation of laser displacement sensors, and the collected data will be inaccurate.

The laser sensor comprises a support, a laser, an imaging objective and a photosensitive element, wherein the laser is arranged on the support through a connecting structure, the laser emits a laser beam to the imaging objective, a laser fixing cavity is formed in the support, a cooling cavity is arranged outside the laser fixing cavity, a mounting part is arranged at the lower part of the cooling cavity, the imaging objective is arranged on the mounting part, the mounting part is connected with the laser fixing cavity through a first connector, the lower part of the mounting part is connected with a second connector, the photosensitive element is arranged on the side wall of the second connector, and the photosensitive element faces the lowerend surface of the imaging objective. The novel laser sensor can work in high-temperature dusty environments and guarantee accuracy of acquired data.

Description

technical field [0001] The invention relates to the technical field of optical measuring devices, in particular to a novel laser sensor. Background technique [0002] Optical sensors are instruments that measure based on optical principles. This type of sensor has many advantages, such as non-contact and non-destructive measurement, almost uninterrupted measurement, high-speed transmission, telemetry, remote control, and real-time processing. advantage. [0003] At present, the sensors that use the principle of laser ranging at home and abroad mainly include: the principle of laser triangulation, pulse method or time division method, and phase laser rangefinder. The principle of the laser triangulation reflection method is that the laser transmitter shoots the visible red laser to the surface of the measured object through the lens, and the laser reflected by the object passes through the receiver lens and is received by the internal CCD linear camera. According to differen...
