The FRAME imaging technology offers the unique ability to acquire and store multiple exposures in one frame of a standard camera sensor. This new Frequency Recognition Algorithm for Multiple Exposures (FRAME) imaging concept uses an image-coding strategy, where different exposures are given a unique structural code allowing multiple on-chip exposures before readout. At the end of such a superimposed recording each image is unlocked by its unique structural code. This on-chip recording of structural coded images opens up a variety of new measurement schemes such as ultra-high-speed imaging, instantaneous 3-dimensional imaging, simultaneous, multispectral imaging.
- 4 images at 1 MHz frame rate using a standard high-resolution camera
- FRAME illumination unit for structural light exposure
- Cost-effective alternative to expensive high-speed cameras
Coded light sheets at different spatial locations are used in combination with FRAME imaging technology for 3D laser imaging of e. g. 3D concentration fields of LIF species in flames.
Simultaneous, multispectral imaging
Performing multispectral imaging with FRAME allows the simultaneous recording of images with different wavelength information. For example, species-specific LIF processes in biological samples can be recorded parallel in time for higher throughput screening.
