Abstract: Disclosed herein is a scanning ladar transmitter that employs an optical field splitter/inverter to improve the gaze characteristics of the ladar transmitter on desirable portions of a scan area. Also disclosed is the use of scan patterns such as Lissajous scan patterns for a scanning ladar transmitter where a phase drift is induced into the scanning to improve the gaze characteristics of the ladar transmitter on desirable portions of the scan area. Also disclosed is a compact beam scanner assembly that includes an ellipsoidal reimaging mirror.

Abstract: A spectrometer design method that corrects aberration by using crossed optical paths and minor alignment, simplifies manufacture by applying the light entrance slit and aperture on opposite sides of a transparent input block, and creates a more compact footprint by placing a 45 degree mirror or right angle prism directly in front of the detector is disclosed.

Abstract: An aperture shaped to provide a narrow beam in the horizontal plane but a wider beam in the vertical plane that will provide improved image quality in spectrometers without sacrificing as much throughput as typically experienced using a reduced diameter round aperture along with a method of mounting the entrance slit and the limiting aperture on a transparent block for optical stability and ease of alignment is disclosed.

Abstract: A method of making specially shaped mirrors for astigmatism correction in spectrometers having a folded optical path using two mirrors by determining the curvature of one or both mirrors in the vertical direction such that the focal length in the sagittal direction of each of said one or both mirrors becomes the same as the focal length in the tangential direction wherein the radius of curvature of each of one or both mirror in the sagittal plane is adjusted to be equal to the radius of curvature in the tangential plane of each of one or both mirrors times the square of the cosign of the angle of incidence of the optical path at each of one or both mirrors is described.
