We present a low-cost alternative to more complex laser metrology systems that uses a
single-mode fiber Fabry–Perot etalon to generate an emission spectrum of evenly spaced …

The primary goal of Galactic archaeology is to learn about the origin of the Milky Way from
the detailed chemistry and kinematics of millions of stars. Wide-field multifibre spectrographs …

We present the design and testing of a prototype in-plane echelle spectrograph based on an
actively controlled fiber-fed double-pass design. This system aims to be small and efficient …

Filtering light from a broadband source with a Fabry–Perot etalon generates comb-like
peaks in the spectral domain that can serve as calibration reference for precise Doppler shift …

High-precision astronomical spectrographs routinely employed to detect planets via the
radial velocity method are generally large and expensive instruments. We present our …

基于多普勒效应的视向速度法是探测太阳系外行星的重要方法, 探测类地岩石行星需要至少10
cm/s 的长期测量精度, 这对波长定标技术提出了较高的要求. 自2008 年锁模激光器天文光梳 …

Over the last few decades, the use of photonic fibers and waveguides in astronomical
instrumentation has grown substantially. This paper provides a summary of the driving …

We review narrowband imaging technologies, with focus on low spectral-resolution systems
customized for observational cosmology over a much wider viewing solid angle than can be …
