Abstract: Sensors, devices, apparatus, systems and methods for replacing microlens arrays with one or more switchable diffractive waveplate microlens arrays for providing measurements of wavefronts and intensity distribution in light beams with high spatial resolution with a single optical radiation sensor. The device acts like a conventional Shack-Hartmann wavefront sensor when the microlens array elements are in focusing state, and the device performs light beam intensity profile characterization acting as a beam profiler when the optical power of lens array elements is switched off.

Abstract: The subject matter disclosed herein pertains to a method for screening drugs using second-harmonic generation microscopy. The tissue is scanned with a pulsed laser light which has an excitation wavelength. At least some of microtubules within the tissue produce generated light with a second-harmonic wavelength that is half the excitation wavelength. A microtubule pattern within the tissue is determined based on an analysis of the generated second-harmonic wavelength.

Abstract: Image-based, monochromatic, wavefront sensing for alignment of the segmented aperture of a telescope can produce segments which are misaligned by multiples of the center wavelength, λ. The phenomenon is well-known and it is called “piston ambiguity” [1]. We call such a misalignment a “piston wrap.”A segmented array, perfectly aligned except for piston wraps, will have perfect imaging at wavelength λ but will have degraded imaging at other wavelengths. The present method detects and corrects piston wraps by making image-based measurements at a second wavelength λ1. These measurements will produce an image of the piston-wrapped segments and the intensities of these segments are linearly related to the size of the piston wraps at wavelength λ.The method needs no additional equipment like inter-segment apertures, lenslets, and detectors. It needs only a narrowband filter to change the measurement wavelength from λ to λ1.

Abstract: In an optics system, a flexible mirror is deformed with an electromagnetic force. In one embodiment, an electrical current is directed through the mirror, or a conductor attached to the mirror, in the presence of a magnetic field. In one application in an adaptive optics system, the membrane mirror is used in a wavefront sensor. Deformed to oscillate between convex and concave positions, the mirror is used to alternately defocus a received light signal for determining aberrations in the light signal. By detecting aberrations in the light signal, the adaptive optics system can correct for those aberrations.
