English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • The Eye
CONT

The Amsler grid is a chart that is specifically designed to qualitatively analyze the disturbances of visual function that accompany the beginning and evolution of maculopathies. The charts are a series of lined and patterned grids that test the central visual field within 10 degrees of fixation where the plates are held at 1/3 of a meter from the eyes. Each square of the grid subtends [one] degree of visual angle, making the ability to define the location of small defects rather easy.... The Amsler grid test is quick and easy to administer. The patient is instructed to look at the central dot and asked if, in fact, he/she can see it. If not, the patient may have a central scotoma, and the examiner must query the patient regarding exactly what he/she "does" see. If the patient sees the dot, the examiner asks if the patient is aware that surrounding it are numerous squares. The examiner then asks the patient if any of the squares are distorted, missing, etc.

CONT

Le test de la grille d'Amsler permet de détecter une DMLA [dégénérescence maculaire liée à l'âge]. En tenant la grille au niveau de l'œil à une distance de lecture confortable et en fixant le point central, les patients atteints voient des lignes déformées, interrompues ou brisées, parfois des zones floues ou aveugles.

Record 3 2007-07-09

English

Subject field(s)
  • Audiovisual Techniques and Equipment
  • Photography
DEF

An exposure meter [that] measures the light Through the Taking Lens of the camera, thus automatically allowing for changes of image angle with lenses of different focal length or at different focusing positions, changes of transmission due to the use of filters, close-up exposure factors, etc.

French

Domaine(s)
  • Audiovisuel (techniques et équipement)
  • Photographie
DEF

[Posemètre] mesurant la lumière qui traverse l'objectif afin de régler l'exposition.

Record 4 2004-08-04

English

Subject field(s)
  • Measuring Instruments
  • Photography
DEF

A luminance meter("reflection"-type "exposure" meter) with a very narrow angle of acceptance so that it can measure a small subject area at a considerable distance.

OBS

Most spot meters are photoelectric, but some are of the comparator type.

French

Domaine(s)
  • Appareils de mesure
  • Photographie
DEF

[...] posemètre [qui] permet de prendre une lecture d'une petit zone (normalement identifiée par un cercle situé au centre du viseur) [jugée] importante, comme une fleur très colorée qui se détache d'un arrière-plan noir.

OBS

Pour activer cette fonction [sur un appareil-photo, on doit] généralement enfoncer le bouton de mesure sélective («mesure spot»), puis activer le posemètre en enfonçant partiellement le déclencheur.

CONT

ACM300-A is the first three-dimensional electromagnetic current meter capable of measuring horizontal and vertical current. The sensor is 20mm in diameter and has many uses such as in complex current experiments, current distribution in a stirrer tub, etc.... The zero point is stable. It has a good range of flow angle. Three-dimensional current analysis is possible with this unique meter.

French

Record 8 1993-09-24

English

Subject field(s)
  • Photography
DEF

Measuring an exposure through a spot meter.

OBS

spot meter : Reflected-light exposure meter which enables the brightness of small areas of the subject subtending an angle of not more than 2[ degrees] to be measured.

French

Domaine(s)
  • Photographie
DEF

Mesure du sujet effectuée avec un posemètre spécial, dont l'angle de mesure est particulièrement étroit.

CONT

La mesure spot permet de mesurer les parties importantes du motif sans prendre en compte les zones de l'image de luminosité très différente qui pourraient éventuellement avoir un effet gênant. Ce type de mesure est utilisé en particulier pour réaliser des contre-jours où la mesure intégrale donne toujours des résultats erronés (...)
