| 2018-04-19 | Martin, Satoshi, Tomohiro | CMOS camera setup | We finished camera angle adjustment for 43 cameras (in total 198). We also shielded bare connectors, put plastic tubes for ~ 100 CMOS cameras and replaced azimuth rotation screws with proper ones. | |
| 2018-04-18 | Satoshi, Tomohiro | CMOS camera setup | We finished camera angle adjustment for 49 cameras (in total 155). We also shield bare connectors, put plastic tubes for many CMOS cameras. | |
| 2018-04-17 | Koji, Satoshi, Tomohiro | CMOS camera setup | We took safety course for working for installing mirrors on site under the local company (Casana). We finished camera angle adjustment for 39 cameras (in total 106). We also shielded bare connectors with small plastic bags, inserted plastic tubes for ventilation, replaced azimuth rotation screws with proper ones and started packing for some cameras. | |
| 2018-04-16 | Satoshi | CMOS camera setup | We finished camera angle adjustment for 13 cameras (in total 67). | |
| 2018-04-12 | Satoshi | CMOS camera setup | We finished camera angle adjustment for 44 cameras (in total 54). | |
| 2018-04-11 | Satoshi | CMOS camera setup | We finished camera angle adjustment for 40 cameras (in total 100). I found angle calculation was not correct. I modified the table and finished adjustment for 10 cameras. | |
| 2018-04-10 | Satoshi | CMOS camera setup | We finished camera angle adjustment for 43 cameras (in total 60). | |
| 2018-04-09 | Koji, Satoshi | CMOS camera setup | We finished attaching CMOS holders for all the 198 cameras. We started camera angle adjustment and finished 17 cameras (in total 17). | |
| 2018-04-08 | Koji, Satoshi | CMOS camera setup | We put loctite on screws of the lens mount for all the 198 cameras. Then we started attaching CMOS holders and finished ~100. We also made a setup for CMOS angle adjustment. | |
| 2018-04-07 | Satoshi | CMOS camera setup | I finished labeling, adjusting lens, IP configuration and IP address table for 198 CMOS cameras. | |
| 2018-04-06 | Satoshi | arrival in La Palma |
Trouble Shooting
2018/04/19
- We spoiled one plus-shaped-head screw and could not loosen and replace it. We replaced the CMOS holder itself with the one (0,+8) we would not install for a while because we could not find a spare one.
- We could insert a CMOS camera which has even an extreme vertical inclined angle (~12deg, in our measurement) into the cutout of a mirror.
- I noticed that in my CMOS angle adjustment setup, the distance between the scale sheet and the camera was 1.3 m, which was not the intended number (1.2 m). This caused ~8 % (0.1/1.2) error for CMOS angles, but I think it is small compared to the FOV of CMOS (±5°,±4°).

- I calculated CMOS angles as the laser spot was at the center of focal plane, which was wrong. I recalculated as it is 1.5 m down from the center and restarted adjustment again.

- Some CMOS cameras have a little rotated images of the scale sheet for angle adjustment. It maybe comes from accuracy of mounting cameras by company.
- Some CMOS cameras have a few dark spots (probably loctite) on their images.

- We had one camera (1/198) which could not be seen from AMC PC.
Tips
2018/04/07
- When adjusting lens, we put loctite on pins for focus, but not for pins for iris.
2018/04/08
- CMOS camera shields are very tight. We cannot screw some of them completely. In that case you can make use of a CMOS holder to fix them tightly.
- Put loctite on screws of lens mount slowly otherwise loctite can be sticked on the lenses or CMOS sensors.
