Optical links for cryogenic focal-plane array readout
An optical link can provide an interface channel for the focal-plane array that is immune to electromagnetic interfer ence (EMI) and can lower the heatload on the dewar. Our approach involves the use offiber-optics and an on$ocal.plane optical modulator to provide an interface to the focal-plane array (FPA). The EPA drives the modulator with an electrical signal. We evaluated specially fabricat...
متن کاملDevelopment of Cryogenic Readout Electronics for Far-Infrared Astronomical Focal Plane Array
We have been developing low power cryogenic readout electronics for space borne large format far-infrared image sensors. As the circuit elements, a fully-depleted-silicon-on-insulator (FD-SOI) CMOS process was adopted because they keep good static performance even at 4.2 K where where various anomalous behaviors are seen for other types of CMOS transistors. We have designed and fabricated sever...
متن کاملFocal Plane Array Optical Focusing and Alignment
A need for active adjustment of a focal plane array (FPA) exists for space based telescopes at Sandia National Laboratories. Legacy systems relied upon manual alignment of the FPA to the optics train. The alignment was done by checking the image then adjusting the position of the FPA with shims, repeated until the desired alignment and focus were achieved. This approach has several drawbacks, i...
متن کاملPrecision Photonic Readout for Focal Plane Signals
We will present the development of a remote Precision Photonic Readout for Focal Plane Array Detectors. Its underlying principles, design and tests as well as limitations will be discussed. The design, in essence, constitutes a remote, via fiber optics, analog-to-digital converter, where the low level focal plane signals are encoded as differential optical phase shifts. These phase shifts are t...
متن کاملFast Focal Plane Array Detector and Readout for Pulsed Opto- Thermal Radiometry
Mid-infrared focal plane array spectroscopic or spatial imaging of opto-thermal transient emission is reported. Pulsed near-surface optical heating of arbitrary unprepared room temperature surfaces produce depth-resolved transient thermal emissions in the mid-infrared chemical fingerprint spectral region. Two optical configurations, both offering a significant advance in pulsed photothermal rad...
