Applied Optics and Optical Design, Parts One and Two - Knovel

The optical lens of a compact disc drive. Optical lens design — refers to the calculation of lens construction parameters variables that will meet a set of performance requirements and constraints, including cost and schedule limitations. Optical flow — The optic flow experienced by a rotating observer in this case a fly.

The direction and magnitude of optic flow at each location is represented by the direction and length of each arrow. Image taken from. Elena A. Natural fluorescence is a very weak signal, which represents only a very small fraction of the light emanating from the surface. The only method to detect natural ground fluorescence is to observe in the Fraunhofer lines of the solar spectrum where the otherwise much stronger reflectance background is significantly reduced.

Table of Contents

Ideally, would a Fraunhofer line be completely dark, the fluorescence would introduce some light at the line position visible on a black background. The spectrometer is calculated for four Fraunhofer lines, any combination of which can be used for the measurements. The first concave pre - dispersing grating focuses the selected lines to the entrance slits. The second part of the device consists of two concave diffraction gratings, one for the blue channel, and one for the red channel. These gratings focus light to the same detector array.

No other optical elements are necessary. Spectrometer shows diffraction limited image quality.

All the gratings surfaces have spherical form. This spectrometer has small dimensions about x x 70 mm and can be attractive for the space applications. Several modifications of the spectrometer and some aspects of its diffraction gratings fabrication and their diffraction efficiency are discussed.

Ray Tracing in an Optical Cavity

The primary mission of Pan-STARRS is the detection of potentially hazardous asteroids PHA , secondary science objectives are a nearly all-sky survey, a medium-deep survey, an ultra-deep survey, and studies of variability. This paper discusses the basic design choice of a distributed system of four telescopes and the details of the optics design. Its main goals are the search of stellar oscillation and the exoplanet detection. Five star fields chosen close to the galactic plane and in the opposite direction will be observed with an high photometric stability.

Four x CCD detectors cover two detection areas one for asteroseismology and the other for exoplanets detection. To avoid the saturation risk the seismology area is just in front of focal plane; in the exoplanet area a low power prism disperses the images to get color information about each observed star. This paper presents the procedure used to deduce the polychromatic PSFs for both the seismology and the exoplanets detection areas depending on position and star color indexes.

The use of standard optical packages, the expected inaccuracies and performances are discussed. The 1. The tight pointing stability performance of 1. The thermomechanical design and the mirror polishing are highly critical issues in the instrument design. The mirror polishing concept and performances are discussed.

Remote sensing of a range of pollutants in the lower Earth atmosphere requires high spectral resolution 0. Sensing of large Earth areas from Geostationary orbit GEO has critical advantages in monitoring the origins and transport of pollution on hourly time scales. The sensor concept is a pushbroom imaging spectrometer using a common all-mirror telescope with a set of three grating spectrometers and area-array detectors. The challenges in optical design include requirements for excellent colour correction to achieve spatial registration over wide spectral bands, and operation at high relative aperture.

These aims are achieved by use of novel spectrometer design concepts, including use of a convex diffraction grating in a concentric configuration. Calibration concepts, including a ratioing technique for absolute measurements, are briefly described. A highly stable frequency-stabilized extended-cavity diode laser for space.

The laser is based on an extended cavity diode laser ECDL. We will present the design, preliminary performances and the environment behaviour of this ECDL. It emits 30mW laser power at a wavelength of nm with a line-width around kHz. The laser frequency is servo-locked on a saturated absorption line of a cesium vapour. According to the results of the mock-up, the flight model under development is expected to be the most accurate and stable laser for space. Beyond the intended application of space-based cold atom clock, such a stabilized laser could also be a key element for future on-board instruments such as space interferometers or space LIDAR, for which a highly stable optical frequency standard is required.

A future atmospheric chemistry sensor: the Limb Infrared Fourier Transform spectrometer. Eric A. Pailharey ; Francois J. Chateauneuf ; Donny M. Natural and anthropogenic trace constituents play an important role for the ozone budget and climate as well as in other problems of the environment. Atmospheric trace aerosol distribution plays an important role in key evolutions of the Earth atmosphere, such as stratospheric ozone depletion and greenhouse effects.

In order to monitor those changes and to try to prevent their dramatic impact, exchange processes between the stratosphere and troposphere as well as the distribution and deposition of tropospheric trace constituents are investigated. This instrument supply observation of species with regard to eight specific questions centred on climate-chemistry interactions and the role of anthropogenic emissions.

LIFT will globally provide calibrated spectra of the atmosphere as a function of the tangent altitude. The users will subsequently retrieve altitude profiles of the target species from the spectra. LIFT field of view will be 30 km in elevation and in azimuth. The resolution of this instrument is 30 km in azimuth corresponding to the full field of view, while it is only 2 km in elevation, obtained by using a matrix of 15x15 detectors.

The instrument will cover the spectral domain 5. With a spectral resolution of 0. Lens Design and Enhancements I.

module specification

Optical design of a Michelson wide-field multiple-aperture telescope. In the Michelson configuration, the instrument is made of sub-telescopes distributed in the pupil and combined by a common telescope via folding periscopes. The phasing conditions of the sub-pupils lead to specific optical constraints in these subsystems. The amplitude of main contributors to the wavefront error WFE is given as a function of high level requirements such as field or resolution and free parameters, mainly the sub-telescope type, magnification and diameter. It is shown that for the periscopes, the field-to-resolution ratio is the main design driver and can lead to severe specifications.

The effect of sub-telescopes aberrations on the global WFE can be minimized by reducing their diameter. An analytical tool for the MAOT design has been derived from this analysis, illustrated and validated in three different cases: LEO or GEO Earth observation and astronomy with extremely large telescopes. The last two cases show that a field larger than 10 resolution elements can be covered with a very simple MAOT based on Mersenne paraboloid-paraboloid sub-telescopes.

Michelson MAOTs are thus a solution to be considered for high resolution wide-field imaging, from space or ground.
