Ultra high frame rate image processing was achieved by applying CNN-UM chips as focal plane array processors. By applying parallel optical input, and reading out binary decision from the chip only the computational overhead is negligible. This makes possible even 50,000 fps image capturing and complex processing. Experiments were done and are described in the paper.

A new Focal Plane Architecture for Motion Computation is presented. The design is based on the Smart Sensor paradigm: combining transduction and early processing at sensor level. The sensor computes focal plane motion and direction in a subsampled space, with programmable spatiotemporal bandwidth. The architecture is designed around an array of neuromorphic analog processing cells with local ph...

A focal plane array designed for real-time, general-purpose, image preprocessing is described. The analog charge-coupled device-based array operates in the charge domain and has sensing, storing, and computing capabilities. It captures the image data and performs local neighborhood operations. The array is digitally programmable and various image preprocessing tasks can be implemented. It uses ...

Experiments measuring the transmission of 5 nanosecond (FWHM), 532 nm pulses through an optical limiter using two different nonlinear materials at two separate focal planes show by far the highest dynamic-range measured to date. This cascaded focus, f/5 optical limiter combines self focusing and consequent nonlinear scattering in CS2, with reverse saturable absorption in lead-phthalocyanine (Pb...

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...

This paper presents a fast and robust method for fixed pattern noise nonuniformity correction of infrared focal plane arrays. The proposed method requires neither shutter nor elaborate calibrations and therefore enables a real time correction with no interruptions. Based on derivative estimation of the fixed pattern noise from pixel sized translations of the focal plane array, the proposed meth...

We present results from laser annealing experiments in Si using a passively Q-switched Nd:YAG microlaser. Exposure with laser at fluence values above the damage threshold of commercially available photodiodes results in electrical damage (as measured by an increase in photodiode dark current). We show that increasing the laser fluence to values in excess of the damage threshold can result in an...

We consider the use of spatial filtering algorithms for radio frequency interference (RFI) mitigation in conjunction with a focal plane feed array of electrically small elements. Numerical simulations are used to study the performance of 7 and 19 element hexagonal dipole arrays with a 25 meter reflector at an operating frequency of 1612MHz. Using the maximum-SNR algorithm to generate array weig...

We propose a new robotic system for positioning payloads such as pickoff mirrors, fibres or deployable IFUs on telescope focal planes. Based on a combination of concepts used in existing fibre positioning systems, the proposed system retains the advantages of each type of existing positioner, while eliminating many of the disadvantages. It employs micro-robotic actuators to independently and si...

In this paper we discuss a choice between the diffractive and refractive binary micro-lenses for the longwave IR FPA. To investigate diffraction on the micro-lenses we have used a numerical code based-on the rigorous electromagnetic theory, because neither geometrical optics nor thin element approach of scalar diffraction theory can correctly describe waveguide, shadowing and interference effec...
