1、 Environmental adaptability requirements

1. Light condition control
   • Avoid direct sunlightSunlight or strong light sources (such as halogen lamps) may interfere with the laser receiver, leading to measurement failure or data deviation. It is recommended to use it indoors or in a shaded environment, or choose equipment with resistance to environmental light interference.
   • Dark environment compensationUnder low light conditions, ensure that the device's infrared auxiliary lighting function is functioning properly to avoid signal loss due to insufficient target reflection.
2. Temperature and humidity management
   • Working temperature rangeMost devices require an ambient temperature between -10 ℃ and 50 ℃,harshTemperature may cause a decrease in laser performance or electronic component failure.
   • humidity controlHumidity exceeding 85% RH may cause condensation, and it is necessary to store the equipment in a moisture-proof box or prevent it through heating and dehumidification functions.
3. Air quality requirements
   • Dust and fog preventionDust, water vapor, or oil mist can scatter the laser beam, affecting measurement accuracy. The use effect is better in clean rooms or dust-free workshops, and dust covers should be equipped when working outdoors.
   • Avoid smokeWelding fumes, chemical vapors, etc. may absorb or refract laser, and should be operated in a ventilated environment.

2、 Target object characteristic matching

1. Surface reflectance control
   • Highly reflective surfaceMirrors, chrome plated metals, etc. may reflect laser light in the wrong direction, resulting in no echo signal. It can be solved by spraying matte paint, using polarizing film, or adjusting the measurement angle.
   • Low reflective surfaceBlack rubber, frosted glass, etc. absorb too much laser and need to use high-power mode or increase measurement frequency to improve signal-to-noise ratio.
2. Material Transparency Treatment
   • Transparent/semi transparent objectsGlass, plastic film, etc. may allow laser penetration, so a reflector should be placed behind the target or a device with a penetration mode (such as a LiDAR) should be selected.
3. Shape and texture influence
   • Curved objectCylinders, spheres, etc. may cause laser reflection path deviation, and multi angle measurement or 3D reconstruction algorithms need to be used for correction.
   • rough surfaceTexture such as sandpaper and fabric can scatter laser light, so it is necessary to increase the size of the measurement spot or use statistical averaging to process the data.

3、 Equipment operation specifications

1. Calibration and preheating
   • Power on preheatingThe laser needs to be preheated for 5-10 minutes to achieve stable output and avoid wavelength drift in a cold state.
   • zero point calibrationBefore use, calibrate the distance reference with a standard target plate (such as a diffuse reflection plate with a reflectivity of 90%). If the deviation exceeds ± 0.1%, recalibration is required.
2. Measurement parameter settings
   • Range selectionSelect the appropriate range based on the target distance (such as 0.1-10m for short distance mode and 10-100m for long distance mode), as measuring beyond the range may cause signal saturation.
   • sampling frequencyWhen conducting dynamic measurements (such as vibration analysis), a sufficiently high sampling rate (≥ twice the target vibration frequency) should be set to avoid frequency mixing.
3. Laser safety protection
   • security levelConfirm the laser safety level of the equipment (such as Class II, Class IIIb). Laser protective goggles must be worn for Class IIIb and above, and direct viewing of the beam is prohibited.
   • Beam pathEnsure that there are no personnel or flammable materials in the laser path, and set up warning signs during outdoor operations.

4、 Personnel and safety regulations

1. Qualification requirements for operation
   • Untrained personnel are not allowed to operate equipment and must be familiar with laser safety regulations, equipment functions, and emergency response procedures.
   • Children and pets are prohibited from entering the measurement area.
2. Personal Protective Equipment (PPE)
   • Laser protectionClass IIIb/IV lasers require wearing protective goggles that comply with ANSI Z136.1 standards.
   • reflective vestWear high visibility clothing during outdoor work to prevent vehicle or equipment collisions.
3. Emergency Response Plan
   • Laser burnImmediately rinse eyes or skin with clean water, and bring the equipment safety manual when seeking medical attention.
   • Equipment failurePress the emergency stop button, disconnect the power, and contact maintenance personnel.

5、 Data collection and processing optimization

1. Multi angle measurement
   • Collect data from different directions for complex shaped objects and improve the accuracy of 3D reconstruction through point cloud registration algorithms.
2. Environmental compensation algorithm
   • Use the built-in temperature and air pressure compensation functions of the device, or manually input environmental parameters to correct the measured values.
3. Post processing validation
   • Compare the measurement results with contact measurements (such as calipers or coordinate measuring instruments), and re measure if the deviation exceeds the allowable range.

6、 Long term maintenance and storage

1. Cleaning and maintenance
   • Wipe the optical window with specialized lens paper after each use to prevent fingerprints or dust from adhering.
   • Regularly check for loose cable connections and oxidized interfaces.
2. Battery Management
   • Lithium batteries retain 50% of their capacity when stored for a long time, and are charged and discharged every 3 months to prevent battery aging.
3. Transportation protection
   • When moving the equipment, use the original packing box, and fix it with foam inside to avoid the optical element offset caused by vibration.
