Abrégé

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.

A computer program product interacts with machine-readable mediums with instructions for automated target recognition. It captures a video of a specified region using detectors on a vehicle. Raw image frames from the video undergo pre-processing, followed by feeding through long and short-range target detection pipelines.

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.
