IR Camera

FLIR Boson performances

ANAFI USA carries a 60 Hz FLIR Boson micro-bolometer. This module is equipped with a mechanical shutter which enables automatic recalibration of the sensor as often as possible, for a complete consistence of each thermal pixel’s response. The lens of the FLIR Boson has a 50° HFOV.

Coloring modes

ANAFI USA’s thermographic camera presents two complementary coloring modes, which enables the drone to adapt to every mission.

Relative mode

The relative mode displays a general view of the thermographic of a scene, on a colored scale, graduated from 0 (dark blue) to 100 (bright yellow).

Spot mode

Only coldest or hottest spots of the image are colorized, depending on the user’s needs.

RBG Camera

Key characteristics of the 2 EO cameras:

  • Wide angle EO camera1/2.4’’
  • RGB: 4K HDR (24 fps)
  • Photo: 21 MP
  • Angular resolution: 0.016°/pixel
  • MTF > 45 % at 160 lp/mm
  • Zoom: 1x => 5x in 1080 p
  • F2.4 aperture 
  • Telephoto EO camera1/2.4’’
  • RGB: 4K HDR (24 fps)
  • Photo: 21 MP
  • Angular resolution: 0.004°/pixel
  • MTF > 45 % à 160 lp/mm
  • Zoom: 5x => 32x in 1080 p
  • F2.4 aperture
  • Continuous 1x to 32x zoom
  • The focal leap between the wide camera (1x to 5x) and the telephoto camera (5x to 32x) is automatic, which guarantees a continuous zoom.

Optical unitWe are using low dispersion aspheric lens architectures (110° and 26° diagonal fields of view, respectively for the wide and tele lenses). The optical units are composed of six lenses optimized to minimize the level of parasitic light while providing a high-resolution image across a vast temperature range (-43 °C to 45 °C). Diagonal (DFOV) and Horizontal (HFOV) fields of viewThe lens of the wide camera covers the full diagonal of the sensor with a 110° DFOV. It brings a 69° HFOV for the standard video mode, and a 75° HFOV for the standard photo mode. The lens of the tele camera covers the full diagonal of the sensor with a 26° DFOV. It brings a 16° HFOV for the standard video mode, and a 16° HFOV for the standard photo mode. Lossless zoom capabilitiesThe conception of ANAFI USA’s optical unit enables the drone to achieve 5x lossless zoom in 4K-UHD (3840x2160 px), 10x lossless zoom in Full HD (1920x1080 px) and 15x lossless zoom in HD (1280x720 px). Finally, at 27x zoom, ANAFI USA images still reach DVD quality (720x480 px). Angular resolution and discernable detailsThe angular resolution of a lens expresses the angular separation between two pixels of the associated sensor. With the angular resolution of 0.004° on its telephoto lens, ANAFI USA enables its users to discern 10 cm (about 4’’) details at a distance of 1,500 m (about 0.93 miles), or 1 cm (about 0.4’’) details at 150 m (about 164 yards).

Optical unit manufacturing: Active alignmentThe optical unit is assembled with the sensor using an Active alignment technique. The optical block is positioned and held in place using a robotic arm, to achieve the following performance: the optical block is positioned above the sensor to ensure the desired focus at a set temperature (23 °C +/- 2 °C) and to guarantee resolution specifications in the scene;in yaw, roll and pitch, the optical block is positioned respecting the optical axis to obtain a uniform resolution on the edge of images;the sensor is aligned with the optical block axis to get the best performance at the center of the image;the optical center is finally aligned with the sensor center (+/- 20 pixels or 22 micrometer). To guarantee the ISP’s image quality specifications, the factory performs an image calibration. In its internal memory, each optical unit carries the optical center, a dead pixel mapping, a lens shading mapping (luminance and color) and white balance.

QualitySeveral optical tests are performed in the course of the production process: MTF checks on the image centerMTF checks on the image bordersCamera module checks while in production:Center MTFMTF at 40 % of the fieldMTF at 70 % of the fieldLight blemishes (dark or light areas on the image, dust suspicions)Dead pixels (checking the total number)Optical centerUniformity of brightness and color in the fieldCosmetic defects (stains, scratches, etc.)
