Abstract

A transparent horizontal gradient freeze (HGF) furnace enables determining a crystallizing growth rate of an ingot by optically monitoring the rate at which a solid/liquid interface traverses across a charge of melted precursor material. The crystallization can be recorded for subsequent analysis, or a machine vision system can monitor and report the solid/liquid traversing rate in near real time, thereby enabling automated regulation of the growth rate to ensure uniform growth. Embodiments implement the disclosed furnace to produce crystalline or polycrystalline indium antimonide mixed with 1.8 wt % nickel antimonide (InSb:NiSb) at a growth rate specified according to required InSb:NiSb properties and a predetermined relationship between the growth rate and the properties of the NiSb needles formed in the ingot. Growth rates can be between 0.02 and 0.08 cm/hr for substantially single crystal ingots, and between 0.5 and 1.5 cm/hr for polycrystalline ingots. The InSb:NiSb can be doped with tellurium.

Abstract

An apparatus for causing a motor to rapidly reorient a rotatable element calculates a desired rotation rate f(θe) as a function of an orientation error θe, and calculates a current Ir that, if applied to the motor, will accelerate and then regulate the rotation rate {dot over (θ)} equal to f(θe). Simultaneously, a maximum current Is is calculated that will not exceed an applicable power limit Pmax or motor current limit. The lesser of Ir and Is is applied to the motor. For large rotations, Is is applied during acceleration until {dot over (θ)}=f(θe), and then Ir is applied during deceleration. Multiple elements can be simultaneously rotated by apportioning Pmax among the elements as they are rotated. The allocated Pmaxi can be larger for elements that require larger rotations, and can be varied during the slew time. The rotatable element can be a gimbal pointer mirror or a Risley prism element.

Abstract

A controller applies iterative ray tracing and root finding to determine an orientation difference Δθd of Risley Prism Assembly (RPA) prism elements required to provide a desired light refraction angle γd. In each iteration, a linear approximation is applied between lower and upper angle difference limits to determine an approximate value Δθa, and ray tracing is applied to determine a corresponding refraction angle γa. Depending on whether γa is greater than or less than γd, the upper or lower angle difference limit is reset to Δθa, and the process continues until convergence. Ray tracing also determines an angular rotation ϕa of a refracted beam about the rotation axis at Δθd, and the orientations of the prism elements are adjusted to provide a desired pointing direction γd, ϕd according to Δθd, ϕd, and ϕa. Prism element imperfections are accommodated in the ray tracing.

Abstract

An apparatus and method of step-scanning frames in a field of interest (FOI) includes continuously rotating prism elements of a Risley prism assembly (RPA) while periodically rotating and resetting a fast-steering mirror (FSM) to provide static pointing during each frame. A gain factor is calculated for each frame according to actual and hypothetical prism element orientations and ray tracing, and the RPA and/or FSM rotation rates and FSM timing are adjusted accordingly. In embodiments, light from the frames is directed to a camera, and the RPA and/or FSM rotation rates and timing are adjusted to maintain adjacent frames with minimum overlap. Calculating the gain factor can include calculating hypothetical prism element rotations by a ray trace and root finding method of false position. The RPA can be achromatic. Step-scanning can be at a constant rate. Frames can be of equal duration, or of durations proportionate to their sizes.

Abstract

In one example, a method of image processing includes acquiring a plurality of input image frames, detecting at least one object of interest in individual image frames of the plurality of image frames, for the individual image frames, producing a respective bounding box corresponding to the at least one object of interest, the bounding box describing coordinates of a boundary of the object of interest within a respective individual image frame, temporally averaging corresponding pixel values of pixels within the bounding box over the plurality of image frames to produce a plurality of averaged pixel values, and producing an output image in which pixels within an area of the output image described by coordinates of the bounding box are replaced with the averaged pixel values.

Abstract

An adaptive filter protocol stored on a non-transitory computer readable medium that is operatively in communication with a processor of a platform. The adaptive filter protocol includes a first processing loop that is operatively in communication with at least one receiving device of the platform for receiving at least one input signal. The adaptive filter protocol also includes a second processing loop that is operatively in communication with the first processing loop and has a deterministic gradient descent optimization logic and an interpolation logic. When the at least one receiving device receives the at least one input signal, the adaptive filter protocol enables the processor to generate a refined match filter parameters that substantially correlates with the initial parameters of the at least one input signal upon completing a plurality of refining cycles of the second processing loop.

Abstract

A communications circuit includes a first circuit block and a second circuit block. The first circuit block includes a first splitter, a first signal path coupled to a first output of the first splitter, a second signal path coupled to a second output of the first splitter, and a first switch configured to couple the second signal path to a third signal path or to couple a fourth signal path to the third signal path. The second circuit block includes a second splitter, a fifth signal path coupled to a first output of the second splitter, a sixth signal path coupled to a second output of the second splitter, and a second switch configured to couple the sixth signal path to the third signal path or to couple a seventh signal path to the third signal path. The third signal path extends between the first and second circuit blocks.

Abstract

A computer program product and corresponding method for targeting one or more points in a three dimensional (3D) model is provided. The computer program product including least one non-transitory computer readable storage medium in operative communication with a computer processing unit (CPU), the storage medium having instructions stored thereon that, when executed by the CPU, implement a process to register the 3D model with a stereoscopic image pair. The steps performed include inputting a first image and a second image that define a stereoscopic image pair into an object targeting program, wherein an object is shown in the first image and the second image, inputting a three dimensional (3D) model of the object into the object targeting program, registering the 3D model to the stereoscopic image pair, and targeting a point associated with or near the object based on the 3D model having been registered to the stereoscopic image pair.
