Claims (6)

1. Mentelmä laseretäisyysmittarin toiminnan koesta-miseksi, johon kuuluu laser valopulssien antamiseksi, sala- 5 malamppu (1) laserin valopulssien annon käynnistämiseksi, kondensaattori (Cl) sähköenergian varastoimiseksi salama-lamppua varten ja säädettävä suurjänniteyksikkö (2) kondensaattorin (Cl) varaamiseksi valittuun tasajännitteeseen (U), tunnettu suurjänniteyksikön (2) antaman tasa-10 jännitteen (U) korottamisesta niin suureen arvoon, että laseriin vaikutetaan, niin että se antaa kaksi valopulssia lyhyellä aikavälillä normaalisti yhden ainoan valopulssin sijasta, jotka valopulssit etäisvysmittarissa tulkitaan mittarista lähetetyksi valopulssiksi ja vastaanotetuksi, 15 heijastuneeksi valopulssiksi.
2. Patenttivaatimuksen 1 mukainen menetelmä laser-etäisyysmittarissa, jossa säädettävä suurjänniteyksikkö (2) on yhdistetty muutettavaan takaisinkytkentäpiiriin (4, Rl, R2, R3) sen antaman tasajännitteen (U) säätämiseksi 20 valittuun arvoon, tunnettu suurjänniteyksikön (2) antaman tasajännitteen korottamisesta mainittuun suurempaan arvoon oikosulkemalla osa takaisinkytkentäpiiriin kuluvasta jännitteenjakajasta koestusta varten sovitetulla vaihtokytkimellä. 2L
3. Laite laseretäisyysmittarin toiminnan koestami- seksi, johon kuuluu laser valopulssien antamiseksi, salama-lamppu (1) laserin valopulssien annon käynnistämiseksi, kondensaattori (C1) sähköenergian varastoimiseksi salama-lamppua varten ja säädettävä suurjänniteyksikkö (2) konden-30 saattorin (Cl) varaamiseksi valittuun tasajännitteeseen (U). Laite toiminnan koestamiseksi on tunnettu vaihto-kytkimestä suurjänniteyksikön (2) antaman tasajännitteen (U) korottamiseksi niin suureen arvoon, että laseriin vaikutetaan, niin että se antaa kaksi valopulssia lyhyellä 35 aikavälillä normaalisti yhden ainoan valopulssin sijasta, minkä lisäksi etäisyysmittari on sovitettu tulkitsemaan ensimmäisen valopulssin mittarista lähetetyksi valopulssiksi ja toisen vastaanotetuksi, heijastuneeksi valopulssiksi.
