KIDSpec，动态电感检测器光谱仪，是一个高灵敏度，中等光谱分辨率的光学近红外光谱仪的概念。它利用光学/IR敏感MKID阵列的固有能量分辨能力，从低分辨率光栅中区分多个阶次。通过充当“阶数分解器”，MKID阵列取代了中阶梯光栅摄谱仪中的交叉色散器。这大大简化了摄谱仪的光学布局，并使狭缝比交叉色散仪器更长（以改善天空减法）。KIDSpec将具有与ESO非常成功的X-shooter仪器类似的功能。它将提供一个R = 4000- 10，000的光谱，覆盖光学和近红外光谱范围（0.4-1.5 µm）。除了“长缝”模式外，IFU还将为空间分辨源提供小（）视场。此外，MKID的光子计数操作及其光子能量分辨能力使读取无噪声光谱具有完美的宇宙射线去除。光谱分辨率将足以消除明亮的夜空线，而不会产生额外的像素噪声，使仪器比同等的基于光电倍增管的仪器更灵敏。KIDSpec将增强许多现有的备受瞩目的科学案例，包括瞬态（GRB，SNe等）。后续工作、微弱天体的红移测定和系外行星的凌日光谱学。此外，它将使独特的科学案例，如超紧凑双星中紧凑物体的动态质量估计。
KIDSpec, the Kinetic Inductance Detector Spectrograph, is a concept for a highly sensitive, medium-spectral-resolution optical through near-IR spectrograph. It uses the intrinsic-energy-resolving capability of an array of optical/IR-sensitive MKIDs to distinguish multiple orders from a low-resolution grating. By acting as an ‘order resolver,’ the MKID array replaces the cross-disperser in an echelle spectrograph. This greatly simplifies the optical layout of the spectrograph and enables longer slits than are possible with cross-dispersed instruments (to improve sky subtraction). KIDSpec would have similar capabilities to ESO’s highly successful X-shooter instrument. It would provide anR= 4000–10,000 spectrum covering the optical and near-IR spectral range (0.4–1.5 µm). As well as a ‘long-slit’ mode, the IFU would provide a small () field of view for spatially resolved sources. In addition, the photon-counting operation of MKIDs and their photon-energy-resolving ability enable a read-noise-free spectrum with perfect cosmic ray removal. The spectral resolution would be sufficient to remove the bright night-sky lines without the additional pixel noise, making the instrument more sensitive than an equivalent semiconductor-based instrument. KIDSpec would enhance many existing high-profile science cases, including transient (GRB, SNe, etc.) follow-up, redshift determination of faint objects and transit spectroscopy of exoplanets. In addition, it will enable unique science cases, such as dynamical mass estimates of the compact objects in ultra-compact binaries.
