What video outputs does Muon support?

The Muon core is only a digital output device.Therefore it can be challenging to obtain the digital data from the small Muon core. The customer will need to create their own processing electronics for their end product. For development purposes a series of hardware will be needed to retrieve the digital data from the Muon core. FLIR uses the Pleora iPort CL-U3 Camera Link to USB3 frame grabber to collect video from the Muon and input into a windows based computer. Additional hardware connected to the Muon is required. We use the Tau Camera Link accessory in combination with a common video processing (CVP) board which is effectively a Tau video board with Muon-specific processing added.

The CVP board allows customers to do additional processing including flat-field correction (FFC) logic, temporal filtering (smart frame averaging), and a more effective 5x5 pixel replacement method. These three additional video processing features are hosted on the CVP board because this board has RAM, processor, and memory and demonstrates what the customer can do with their own processing electronics while using a Muon core.

The CVP/Camera link combination makes it possible to output the 16 bits of CMOS digital data in camera link format that can then be input into a standard PC running normal image processing tools. The Pleora frame grabber is just one of many Camera Link frame grabbers that the customer may choose to use.

The Pleora frame grabber does not have an automatic gain control (AGC) function which converts the 14-bit video data to 8-bit data which can be displayed on the computer. The Pleora frame grabber’s 14-bit video therefore has very little contrast and the scene image is hardly noticeable. Another software application should be used to analyze the data and view the relevant 8-bit portion that can be displayed on a normal 8-bit video monitor.

FLIR’s demo kit uses the FLIR ResearchIR windows based software package for additional functions such as image capture, video capture, line profiles, and an AGC function. Note: The Muon core has a 14-bit sensor with additional two bits (total of 16-bits) to provide LWIR thermal data. The additional 2 bits are used for bad pixel identification of the sensor array (alternatively the user can read out the bad pixel map via I2C function and store the information on the host processing hardware).
