High speed Videostroboscope

Principle

The Video­stro­bo­scope is used for visua­liz­a­ti­on and record­ing of vibra­ti­ons and rota­ti­ons in slow-moti­on → on shaker, test ben­ches, at non-acces­si­ble loca­ti­ons (endo­scope-use) and on lar­ge or micro objects. It is an easy-tou­se turn­key sys­tem and pro­vi­des a low cost alter­na­ti­ve to high speed came­ras. No need for flash lights per­mits day light use. It allows auto­ma­tic moni­to­ring and pro­vi­des a wide ran­ge of ana­ly­sis tools. In com­bi­na­ti­on with our spe­cial nano­se­cond light pul­ses it can be app­lied for fre­quen­ci­es up to 100 kHz as well as for high speed rotations.

Advantages of Videostroboscope to the classical light Stroboscope

Auto­ma­ted moni­to­ring: Image ana­ly­sis per­mits auto­ma­tic pro­cess con­trol of test set­ups or in
pro­duc­tion via sen­si­ti­vi­ty to object loca­ti­on or vibra­ti­on ampli­tu­des or pha­se (plea­se ask for details).

Record­ing: Sequen­ces or sin­gle shots can be recor­ded and stored digi­tal­ly. The images or sequences
(avi, jpg etc.) can be fur­ther pro­ces­sed and inclu­ded to pre­sen­ta­ti­ons. Com­pa­red to con­ven­tio­nal High
Speed came­ras this can be done over a very long peri­od as the image stre­em is recored to the computer
memo­ry or hard-disks direct­ly. Using solid sta­te dri­ves (SSD) this is pos­si­ble with high frame rates an
reso­lu­ti­ons e. g. over 200Hz at VGA.

Micro-objects: App­ly­ing zoom­len­ses or micro­scopes per­mit magni­fi­ca­ti­on of small objects.

Quan­ti­ta­ti­ve eva­lua­ti­on: The images inclu­de infor­ma­ti­on for com­pa­ri­son of objects or sta­tes. Image pro­ces­sing tools such as auto­ma­ted edge detec­tion or cor­re­la­ti­on and
mea­su­re­ment tools per­mit quan­ti­ta­ti­ve eva­lua­ti­on of vibra­ti­on ampli­tu­des. No need for dark rooms, no eyes­train: In oppo­si­te to con­ven­tio­nal sys­tems based on flash lights,
the video-stro­bo­scope enab­les the user to work without eyes­train e. g. under day­light. High power flash lights are harm­ful for the eyes allowing short app­li­ca­ti­on peri­ods only.

Secu­ri­ty and image trans­mis­si­on: The obser­ver can be spa­ti­al sepa­ra­ted from the object or dan­ger zone by remo­te con­trol­led ver­si­ons (e. g. engi­ne test stands). Object-obser­ver distance up to 70m (unli­mi­ted using glass fibre).

Envi­ron­men­tal: Ope­ra­ti­on is pos­si­ble under extre­me con­di­ti­ons (e .g. cli­ma­tic chambers).

Acces­si­bi­li­ty: The came­ras can be instal­led on loca­ti­ons with dif­fi­cult access for the human eye. Endo­scope access­ories for came­ras are available.
