Title (EN) LASER ALTIMETER AND PROBE HEIGHT SENSOR
(FR) ALTIMETRE A LASER ET DETECTEUR DE HAUTEUR D"UNE SONDE
Abstract: front page image
(EN)Arrangement to measure precisely probe-to-model board distance in a simulator. A source of radiation (17) is positioned to emit a beam (19) toward a model board surface (20) on which a scaled terrain model is constructed. A fixed position lens (15) collects reflected radiation and directs it onto a sensor device (16) which develops an electrical signal indicative of displacement of the reflected beam, which, in turn, varies directly as the distance between the probe (10) and the model board surface. One embodiment describes an arrangement in accordance with the Scheimflug condition whereby focus is maintained without concern for the depth of field as the probe approaches and withdraws from the surface of the model board.
(FR)Un dispositif sert a mesurer de maniere precise la distance entre la sonde et le modele dans un simulateur. Une source de radiation (17) est positionnee pour emettre un rayon (19) vers une surface d"un modele (20) sur laquelle un modele de terrain a l"echelle est construit. Une lentille de position fixe (15) recupere la radiation reflechie et la dirige sur un dispositif detecteur (16) qui developpe un signal electrique indiquant le deplacement du rayon reflechi qui, a son tour, varie directement en fonction de la distance entre la sonde (10) et la surface du modele. Un mode de realisation decrit un dispositif selon la condition de Scheimflug permettant de maintenir la mise au point independamment de la profondeur de champ au fur et a mesure que la sonde s"approche et s"eloigne de la surface du modele.
