Partitioned-Interval Quantum Optical Communications Receiver
The receiver structure described here improves upon the performance of optical communications
links, achieving high sensitivity and high data rates even with extremely weak optical signals.
The proposed quantum receiver in
this innovation partitions each binary signal
interval into two unequal segments: a
short “pre-measurement” segment in the
...

Cobra Fiber-Optic Positioner Upgrade
This technology could be used for applications requiring precise location of a small object
within a small circular area, such as in medical lasers.
A prime focus spectrometer (PFS),
along with corrective optics, will mount
in place of the secondary mirror of the
Subaru telescope on Mauna Kea,
...

Practical UAV Optical Sensor Bench With Minimal Adjustability
A multiple-pass optical platform eliminates
essentially all optical alignment
degrees of freedom, save one. A fourpass
absorption spectrometer architecture
is made rigid by firmly mounting
dielectric-coated mirror prisms with no
alignment capability to the platform.
The laser diode beam is collimated by a
small, custom-developed lens, which has
only a ...
