[PPS08-P09] Objective and Current Development Status of Multi-Band Camera on SLIM
Keywords:Moon, SLIM, reflectance spectra, Olivine
After landing, SLIM project is planning to observe around landing site using Multi-Band Camera (MBC). The observational mission is positioned as extra success. MBC will observe olivine and estimate Mg# of it. MBC is a compact VIS-NIR camera composed of an imaging sensor (InGaAs), a filter-wheel with 10 band-pass filters, a telephoto optical system, and a movable mirror for panning and tilting. The sensor has sensitivity at wavelength from 700 to 1700 nm, which covers the characteristic ab-sorption bands of lunar minerals. The telephoto optical system can focus on an object from 1.5 to 30 m distance. The imaging sensor has 640 × 512 pixels with 20 µm pitch. The 4º field of view corresponds to the spatial sampling of 1.3 mm per pixel at 10 m from the lander. Using the movable mirror, observable scanning area is ~50º in azimuth and ~70º in elevation. This makes it possible to observe the size distribution of boulders around the lander. The observation wavelength of band pass filters were selected 10 bands: 750, 920, 950, 970, 1000, 1050, 1100, 1250, 1550, and 1650 nm. The width of their bands is 30nm.
