Key Features of a Pulsed Laser Sensor

Principles:

• Time-of-flight method
• Near-infrared wavelength
• Pulsed diode laser transmitter
• Sensitive narrow-band optical receiver
• Single pulse or multiple pulse signal detection
• Microprocessor-based post-processing and interfacing
• As far as appropriate: opto-mechanical scanning mechanism

Advantages

• Small size
• High reliability
• High interference immunity
• High accuracy
• Long range
• Quick data acquisition
• Highly collimated measuring beam
• Excellent cost / performance ratio

Trade-Off:

Reduction of the maximum range due to:

• Very bright daylight
• Bad visibility
• Dirty or dusty front lenses

Two standard units available from HiTECH are: VLM200 and LDM301
