Infrared Movies

Properties of Infrared Movies
  
An infrared movie has the same video properties as a visual movie.  A stream of 
video data generated by an infrared camera is saved as a series of frames.  Each 
frame is a captured video image.  The elapsed time taken by a frame is determined 
by the frame rate of the camera.  At 30 frames per second, each frame has captured 
an event that is at most 1/30 of second in length. 

Requirements for taking infrared movies using non-firewire cameras

An infrared camera with a parallel output is connected to a PCI capture card installed 
on a computer.  The taking of an infrared movie is done by selection of a function such 
as save movie.  Viewing saved infrared movies is accomplished by using a software module 
that has these controls: rewind to beginning or end; Fast Play forward or backward; step 
forwards or backward-- one frame for each mouse click; Slow Play forward or backward; Edit; 
Mark Frames; and Stop.

Requirements for taking infrared movies using firewire cameras 

ThermoSoft II will also work with Flir Cameras that have Firewire interfaces.  Cameras 
utilizing Firewire interfaces have an advantage of requiring no capture card, thus making 
it possible to operate on laptop computers with the obvious advantage of portability. 

Editing and Processing

The user can individually select any frame that comprises an infrared movie and perform on 
this frame all the functions of the software. See the ThermoSoft II brochure for more information.  
A slider bar makes it easy to search through the thousands of frames that make up a long movie.  

Usefulness of Infrared Movies

Replaying infrared movies from the beginning gives users the ability to arbitrarily go back 
in time and observe the infrared properties of the object at that point in time.  Since frame 
capture rates can be adjusted an installation can observe something for days, even months. 
Using the built in EVENT MANAGER within Thermosoft II, almost any kind of input, including 
temperature, can be used to trigger a series of periodic movie clips for storage and 
later evaluation.
 
Frame Rates

With some adjustments, given the capabilities of this software function,
frame rates significantly higher than 60 FPS are realizable. 

Applications

This function has found uses in Steel processing, Tire Testing Labs, flame propagation studies
and medical applications.
