We developed a compact imaging Fourier transform infrared (FT-IR) spectrometer based on wavefront-division interferometry for planetary exploration and small-satellite missions. The instrument covers 4–20 μm with a wavenumber resolution of 3.8 cm−1 and a spatial resolution of 34 μm. The optical system uses two Zernike...

GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is an ISAS/JAXA Strategic L-class mission candidate for the 2030s. The 1.0 m primary mirror, 50 K cryogenic telescope will have a wide-field camera (WFC) with a 0.5 square degree field-of-view in the 2–8 μm wavelength band. An optional high-re...

IR-SOIPIX is a monolithic mid-infrared (MIR) image sensor developed using a standard CMOS process on a silicon-on-insulator wafer. Unlike conventional hybrid detectors that require indium bump bonding, IR-SOIPIX integrates the detector and readout circuitry in a single chip, reducing manufacturing complexity and cost....
High-resolution spectroscopy of molecular lines in the mid-infrared fingerprint region allows innovative science cases, such as surveying snowline locations in protoplanetary disks, but poor atmospheric transmission in this range hinders sensitive, continuous ground-based observations. We are proposing the High-Resolut...
