Abstract: The invention relates to a spectroscopy system and improved membrane formation techniques. The system has at least one light source operable to generate a source beam and a prism having a rear surface. A support block is disposed on the rear surface of the prism. The support block is formed with at least one sample well having a center and defines a substantially vertical rear cell surface having a center. The source beam is aimed at the sample well. A syringe filled with a membrane solution and having a needle with a distal end disposed in front of the sample well. The distal end is aimed at a point above the center of the rear cell surface. The syringe is operable to eject a steady stream of membrane solution from the needle onto the circular rear cell surface thereby forming a membrane defining at least a portion of a layer under test. The membrane has a substantially uniform thickness that covers substantially the entire rear cell surface.

Abstract: The invention relates to a surface plasmon resonance system method. The system has at least one light source operable to generate a source beam, a prism having a rear surface at least partially coated with a metallic coating and optionally a dielectric layer. At least one layer under test is positioned on the rear surface of the prism. The source beam is directed at the layer under test thereby defining an angle between the source beam and the rear surface of the prism. A detector is operable to detect light that is reflected or scattered by the layer under test. The source beam is directed towards the layer under test at a selected angle. The source beam is also shifted in at least one plane to illuminate a specific portion of the layer under test based on the selected relative angle and the position of the layer under test on the rear surface of the prism. The rear surface of the prism can be illuminated in one-dimensional or two-dimensional array like fashion.

Abstract: The piston error problem in a multi-laser optical system having a plurality of parallel component beams is solved by a control loop that responds to a path length difference signal generated by the interference of two of the component beams to adjust one of a set of adjustable component mirrors to reduce the path length difference.

Abstract: A laser wavefront control system employs a common optical path and common high-power deformable mirror to optically compensate an incoming beacon or retroreflected return beam and a laser sample beam, in which the phase conjugate of the laser sample beam is impressed on a low-power deformable mirror. This control system drives the high-power deformable mirror, and has as its input the phase modulation required for compensation of optically sensed wavefront phase errors.

Abstract: A phased array telescope system is permitted to have a larger field of view by simultaneous compensation of piston error and exit pupil location to properly combine the sub-images from the telescopes with the correct lateral displacement and correct magnification to preserve Lagrange invariance between the separate telescopes in the system.

Abstract: An autoalignment system for an unstable laser resonator includes means for measuring the angular position of a convex mirror and adjusting the concave mirror to a new optic axis defined by the convex mirror.
