DLRF measures distance range to targets from 50m to 1500m reliably. DLRF uses a Low power, narrow pulse and eye safe LASER. This system measures distance range to targets from 50m to 1500m accurately and reliably. This system is light weight and consumes low power. The system offers an optional interface to a computer using RS232/RS422/RS455 port using which parameters of the system such as Laser Power, Pulse Repetition Frequency (PRF), Pulse Width, no. of integrations and the Barker codes can be programmed. Operating at a wavelength of 1550nm, the DLRF-1.0 is Eye-Safe and is not easily detectable.
