Abstract

OrganiCam is a laser-induced luminescence imager and spectrometer designed for standoff organic and biosignature detection on planetary bodies. OrganiCam uses a diffused laser beam (12° cone) to cover a large area at several meters distance and records luminescence on half of its intensified detector. The diffuser can be removed to record Raman and fluorescence spectra from a small spot from 2 m standoff distance. OrganiCam's small size and light weight makes it ideal for surveying organics on planetary surfaces. We have designed and built a brassboard version of the OrganiCam instrument and performed initial tests of the system.

摘要

OrganiCam是一款激光诱导发光成像仪和光谱仪，专为在行星体上进行远距离有机和生物特征检测而设计。OrganiCam使用扩散激光束（12°圆锥角）在数米距离处覆盖大面积区域，并在其增强型探测器的一半上记录发光情况。可移除扩散器，以便在2米远距离处从小光斑记录拉曼光谱和荧光光谱。OrganiCam的小尺寸和轻重量使其成为探测行星表面有机物的理想选择。我们已经设计并制造了OrganiCam仪器的原理样机版本，并对该系统进行了初步测试。
