Key Details
Official Description
Quantum communication systems, quantum-enhanced LiDAR, and quantum sensing platforms share a critical and unmet instrumentation need: a spectrometer capable of simultaneously achieving large étendue (high optical throughput) and high spectral resolution. In satellite-based and ground-based quantum key distribution (QKD), ground station receivers must collect single photons from spatially extended fields of view — demanding large étendue — while rejecting broadband background noise, including sol...

Large Étendue, High Spectral Resolution Asymmetric Spatial Heterodyne Interferometer for Quantum and Dual-Use Remote Sensing Applications
# Key Changes for Applicants ## Scope & Technical Focus - **Removed "quantum-enhanced"** qualifier from remote sensing; now just "atmospheric and oceanic remote sensing" — broadens application relevance beyond quantum-only systems - **Shifted from open wavelength range (400–1600 nm) to narrowly constrained single wavelength: 467–533 nm only** — major restriction eliminating 780 nm, 1550 nm, and other previously acceptable bands - **Replaced abstract performance goals with rigid system specifications:** - Étendue increased: 0.1 → 0.35 cm²-sr - Spectral resolving power (R > 10⁵) replaced with specific path difference offset (7.5 cm ±1.5 cm), fringe count (10–20), and visibility (≥0.8) - New bandpass filter requirement: 150 pm max - New sensor constraint: 25 mm² square detector array (fixed, not negotiable) ## Design Requirements (New Constraints) - **Ather
