Abstract

The SuperCam instrument suite provides the Mars 2020 rover, Perseverance, witha number of versatile remote-sensing techniques that can be used at long distance as wellas within the robotic-arm workspace. These include laser-induced breakdown spectroscopy(LIBS), remote time-resolved Raman and luminescence spectroscopies, and visible and in-frared (VISIR; separately referred to as VIS and IR) reflectance spectroscopy. A remotemicro-imager (RMI) provides high-resolution color context imaging, and a microphone canbe used as a stand-alone tool for environmental studies or to determine physical propertiesof rocks and soils from shock waves of laser-produced plasmas. SuperCam is built in threeparts: The mast unit (MU), consisting of the laser, telescope, RMI, IR spectrometer, andassociated electronics, is described in a companion paper. The on-board calibration targetsare described in another companion paper. Here we describe SuperCam’s body unit (BU)and testing of the integrated instrument.The BU, mounted inside the rover body, receives light from the MU via a 5.8 m opti-cal fiber. The light is split into three wavelength bands by a demultiplexer, and is routedvia fiber bundles to three optical spectrometers, two of which (UV and violet; 245–340 and 385–465 nm) are crossed Czerny-Turner reflection spectrometers, nearly identical to theircounterparts on ChemCam. The third is a high-efficiency transmission spectrometer containing an optical intensifier capable of gating exposures to 100 ns or longer, with variable delaytimes relative to the laser pulse. This spectrometer covers 535–853 nm (105–7070 cm−1Ra-man shift relative to the 532 nm green laser beam) with 12 cm−1full-width at half-maximumpeak resolution in the Raman fingerprint region. The BU electronics boards interface withthe rover and control the instrument, returning data to the rover. Thermal systems maintain awarm temperature during cruise to Mars to avoid contamination on the optics, and cool thedetectors during operations on Mars
