Description

Time-of-flight (ToF) optical methods for measuring distance with high precision are utilized in a variety of applications, such as laser safety scanners, range finders, drones, and guidance systems. This design details the advantages of a high-speed data-converter-based solution, including target identification, relaxed sample-rate requirements, and a simplified signal chain. The design also addresses optics, driver and receiver front-end circuitry, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and signal processing.

Features
  • Measurement range up to 9 m or greater
  • Range measurement mean error of <±6 mm and standard deviation of <3 cm
  • 5.75-W pulsed 905-nm near-infrared laser diode and driver with <1-mW average output power
  • Laser collimation and photo receiver focusing optics
  • Includes 14-bit, 125-MSPS ADCs and 16-bit, 500-MSPS DAC high-speed amplifiers and clocking
  • Pulsed ToF measurement method with DFT-based range estimation
  • Automotive grade versions available for select devices
