Compact spectrometers are crucial in areas where size and weight may need to be minimized. These types of spectrometers often contain no moving parts, which makes for an instrument that can be highly durable. With the recent proliferation in low-cost and high-resolution cameras, camera-based spectrometry methods have the potential to make portable spectrometers small, ubiquitous, and cheap. Here, we demonstrate a novel method for compact spectrometry that uses an array of etalons to perform spectral encoding, and uses a reconstruction algorithm to recover the incident spectrum. This spectrometer has the unique capability for both high resolution and a large working bandwidth without sacrificing sensitivity, and we anticipate that its simplicity makes it an excellent candidate whenever a compact, robust, and flexible spectrometry solution is needed.
紧凑型光谱仪在需要最小化尺寸和重量的领域至关重要。这些类型的光谱仪通常没有移动部件，这使得仪器具有高度的耐用性。随着低成本、高分辨率相机的普及，基于相机的光谱测量方法有可能使便携式光谱仪变得小巧、无处不在且廉价。在这里，我们展示了一种使用阵列法布里-珀罗标准具进行光谱编码，并使用重建算法来恢复入射光谱的新型紧凑型光谱测量方法。该光谱仪具有高分辨率和大工作带宽的独特能力，而不会牺牲灵敏度，我们预计其简单性使其成为在需要紧凑、稳健和灵活的光谱测量解决方案时的绝佳选择。
