Plants-go-round : A kinematic system for time lapse photography of seep capsules using a single camera (English)
Abstract [en]

The Swedish University of Agricultural Sciences studies the effects of gene modifications on seeds. When monitoring the growth of these seeds they are using a technique called time lapse photography. It means in this case taking one photo each hour of the seeds, placed on a transparent plastic plate and growing in a medium which supplies nutrition. Thenthese frames are compiled to a movie in which several days of growth are reduced to half a minute.

A system for this already exists and is in use at SLU here in Umeå, but it only has the capacity for one plate at each time. With this system it is increased to 8 plates at a time. It consists of 8 plate holders made of steel. These are attached to a round aluminium disc, which is attached to a rotary table. This table is driven by a 24 volts stepper motor, controlled by a microprocessor programmed in C.

The plants cannot be exposed to visible light, so the lightning is realized with infrared diods.

The camera is controlled from the microprocessor, with a program similar to the function of aintervalometer. The intervalometer is connected directly to the camera for remote controlled photography according to a set time scheme.

The specifications set in the project plan have been fullfilled and the system is doing what it is designed for.

My thoughts about improving the system is to make it easier to use. Via a simple display and a few buttons you can input all the variables needed to use it.
