This paper addresses the necessary procedures that need to be considered when designing an optical sub-system of low concentrator photovoltaic (LCPV) module. CPV systems make use of optical elements and solar tracking to concentrate solar flux onto a photovoltaic (PV) receiver. The performance of a concentrator module is highly dependent on the configuration and alignment of the optical elements in the system. In this study, various design considerations were taken into account to construct a LCPV module that was characterised with respect to optical design and electrical performance

Optical Alignment

An extreme-ultraviolet (XUV) double-stage Raman spectrometer is permanently installed as an experimental end-station at the PG1 beamline of the soft X-ray/XUV free-electron laser in Hamburg, FLASH. The monochromator stages are designed according to the Czerny–Turner optical scheme, adapted for the XUV photon energy range, with optical elements installed at grazing-incidence angles. Such an optical scheme along with the usage of off-axis parabolic mirrors for light collimation and focusing allows for aberration-free spectral imaging on the optical axis. Combining the two monochromators in additive dispersion mode allows for reaching high resolution and superior stray light rejection, but puts high demands on the quality of the optical alignment. In order to align the instrument with the highest precision and to quantitatively characterize the instrument performance and thus the quality of the alignment, optical laser interferometry, Hartmann–Shack wavefront-sensing measurements as well as off-line soft X-ray measurements and extensive optical simulations were conducted. In this paper the concept of the alignment scheme and the procedure of the internal optical alignment are presented. Furthermore, results on the imaging quality and resolution of the first monochromator stage are shown.

A schematic solution of a two-channel optical scheme of the sight, providing simultaneous representation in the field of view of two zones with different magnifications is proposed, while a discrete magnification shift is implemented in the higher magnification zone. A method of organizing the introduction of amendments and reconciliations is proposed, which ensures that when changing the direction of the sighting line in the space of objects, placing an image of the aiming mark in the center of the field of view of each of the zones.

Infrared Imager

An infrared imager measures radiations emitted by an object in specified spectral bands to determine change in object’s characteristics over a period of time. A typical infrared imager consists of focusing optics and a cryogenically cooled two-dimensional infrared detector array mounted on the cold tip of an active micro-cooler vacuum sealed with an optical window, typically known as integrated detector cooler assembly (IDCA). Detection of feeble radiant flux from the intended target in a narrow spectral band requires a highly sensitive low noise sensor array with high well capacity. However, in practical applications the performance of an infrared imager is limited by the parasitic thermal emissions from optical elements and emissions from IDCA components like vacuum window, Dewar walls which are generally kept at ambient temperature. To optimise the performance of imager it becomes imperative to estimate these parasitic fluxes and take corrective actions to minimise their effects. This paper explains an analytical model developed to estimate parasitic fluxes generated from different components of a long wave infrared imager. Validation of the developed model was carried out by simulations in ZEMAX optical design software using ray trace method after analytical computations in MATLAB.

AbstractThe primary objective of the 2-m National Large Solar Telescope (NLST) is to study the solar atmosphere with high spatial and spectral resolution. With an innovative optical design, NLST is an on-axis Gregorian telescope with a low number of optical elements and a high throughput. In addition, it is equipped with a high order adaptive optics system to produce close to diffraction limited performance.NLST will address a large number of scientific questions with a focus on high resolution observations. With NLST, high spatial resolution observations of prominences will be possible in multiple spectral lines. Studies of magnetic fields, filament eruptions as a whole, and the dynamics of filaments on fine scales using high resolution observations will be some of the major areas of focus.

Lithography Technique

Diffractive Optical Elements (DOE) are often associated with the use of laser beam shaping equipment. They can be controlled and verified flexibly according to application. This paper demonstrates experimentally the lithography technique used to fabricate a DOE with precisely aligned pattern on a polymer surface. We have designed and fabricated a grating on the lens surface using the direct lithography by an Atomic Force Microscope. A description of the optical design is presented along with a discussion on the integrated manipulation system. The fabrication process has been proven to be cost efficient and reliable. It is believed that this technique can also transfer onto a complicated DOE.

We present a linear optical scheme for implementing two-bit discrete quantum Fourier transform based only on simple linear optical elements, a pair of two-photon polarization entangled states, and the conventional photon detectors that only distinguish between the presence and absence of the photons. The scheme can be implemented with a certain success probability, and the implementation of the scheme in experiment would be an important step towards more complex linear optical quantum computation.
