The MicroFlir is an ultra compact 8-12 micron waveband thermal imager based on the CVROS scanner. It is shown below in exploded view which shows all the optics plus drive motor for the scan disc (dimple disc) and drive motor (galvanometer) for the framing mirror.
The photograph below shows the completed assembvly for the prototype thrmal imager.It includes provision for matng to a telescope.
The ray trace for the scanner coupled to a telescope is shown below.
Below is a photo of one such telescope. Telescopes of varying magnification and aperture are possible.
The MicroFlir with a large aperture telescope in compact configuration for gimbal mount:
Electronics are required to power and control the motors for horizontal and vertical scanning, to power the cooler for the detector, process the signal and interlace with external power and control devices.. The system block diagram appears below.
The electronics comprise three cards as shown below.

It did not become the U.S. Navy’s choice for submarines, however; they optied for a veey large photonic sensor, an “ash can on a post”., as dubbed by some.. The MicroFlir did however gain acceptance with several overseas institutions.
