| The imager works by reflecting laser light from millions of different points on the object being scanned. |
| It's a thermal imager that can detect termites behind walls and in other hard-to-reach places. |
| Due to spatial frequency heterodyning, upper and lower side band information falls in the pass band of the imager. |
| When a target of interest is located in the super-wide image, the fourth imager with a narrow-field-of-view can be downlinked to provide positive target identification. |
| By using more than one lens when it scans surfaces, the imager divides the spectrum of visible light into four sections. |
| Opportunity moved her arm into position, rotating the turret to aim the microscopic imager down toward the patch. |
