Abstract

Abstract An altimeter is a critical instrument in planetary missions, for both safe operations and science activities. We present required specifications and link budget calculations for light detection and ranging (LIDAR) onboard the Martian Moons Exploration (MMX) spacecraft. During the mission phase, this LIDAR will continuously measure the distance between the spacecraft and its target. The time-series distance provides important diagnostic information for safe spacecraft operations and important information for geomorphological studies. Because MMX is a sample return mission, its LIDAR must accommodate physical disturbances on the Martian satellite surface. This resulted in changes to the optical system design. Graphical abstract

Abstract

Flash LiDAR is a relative navigation sensor that irradiates a target with pulsed laser light and then detects the reflected light to measure intensity, direction, and distance as a time of flight. We are developing “Flash LiDAR” for a space rendezvous. It employs a 3D image sensor that has a multi-pixel photon counter with photon-counting sensitivity and a readout IC with sub-nanosecond time of flight resolution. We conducted a feasibility study with a breadboard model to confirm it could satisfy functional and performance requirements of the HTV-X berthing mission, under limited configurations entailing a short range, a narrow field of view, and no relative position/attitude rate. We then obtained excellent performance results that satisfy the requirements of the HTV-X berthing mission. In this paper, we describe an overview and the features of our Flash LiDAR, the results of preliminary design and breadboard model tests, and the applicability to future space exploration missions.

Abstract

We have developed a compact three-stage Ti:sapphire amplifier laser system that produces a peak power in excess of 100 TW for a pulse duration of less than 19 fs and an average power of 19 W at 10 Hz repetition rate. The spatial beam quality is about twice the diffraction limited for the full amplified, compressed output pulse.
