The defendant, a resident of Illinois, who was in Boston for a convention, received a citation for speeding. The citation indicated that the defendant was allegedly caught on Lidar traveling 61 mph in a 45 mph zone. The client hired Attorney Topazio. LIDAR is an acronym for LIght Detection And Ranging. A police laser emits a highly focused beam of invisible light, in the near infrared region of light that is centered at 904nm of wavelength and is only about 22 inches (56cm) in diameter at 1000 feet (300m). Unlike police RADAR which directly determines a vehicle’s speed by measuring its doppler shift, police laser-lidar calculates speed by observing the changing amount of time is takes to “see” reflected pulses of light over a discreet amount of time. Today after a Clerk’s hearing, Attorney Topazio convinced a Clerk Magistrate to find his client not responsible.
