Sony IMX455 Sensitivity
The sensor G sensitivity of SkyEye62AC is 484.18mV with 1/30s. Its spectral
sensitivity is shown in Figure 2.
16Bit ADC and ROI
The SkyEye62AC has built in 16bit ADC. It also has 12bit output mode for
hardware binning and smaller resolution. The camera also supports hardware
ROI, and the smaller the ROI size is, the faster frame rate is.
Table 2 SkyEye62AC Frame Rate at Different Resolution/Data Bit/Data
Transfer(USB3.0/ USB2.0)
DDR3 Buffer
SkyEye62AC camera has a 512MB (4Gb) DDR3 buffer, which helps maintain the
stability of data transmission, because image data can be temporarily buffered
without being sent hastily to the receiver.
Binning
The SkyEye62AC supports digital binning from 11 to 88 in either stacking or
averaging method, and hardware binning from 11 to 33 in averaging method.
Hardware pixel binning is much faster than software binning.
Conversion Gain Switch
SkyEye62AC supports HCG and LCG mode switch. Under LCG mode, the full well can
reach 107ke-.
Power and Cooling System for Precise Temperature Regulation
USB3.0 is used for the camera driving and data transfer.
The cooling system of SkyEye62AC is two-stage Thermoelectric Cooling (TEC)
with controllable electric fan assisting heat dissipation. The working
temperature can be regulated to specific number, and effective temperature
drop can be e -35°C from ambient temperature. Such efficient cooling system
guarantees the stability of ultra-low noise mode and quality of the camera
image.
The TEC system is controlled by PID algorithm, which allows the TEC to be
precisely regulated towards the target temperature with 0.1C deviation.
Zero Amp-Glow
The SkyEye62AC has been carefully designed and is able to achieve zero amp-
glow photo shooting. Figure 3 and Figure 4 show the different cameras at 20C
and 5-minute exposure time with and without amp-glow. One can find that
SkyEye62AC captured image has zero amp-glow.
Camera Performance Analysis
Camera performance can be evaluated with e-/ADU, Read Noise, Full Well and
Dynamic Range.
e-/ADU: The sensors found in cameras used for vision applications have pixels
that convert incoming photons into electrons. Gain on a CCD /CMOS camera
represents the conversion factor from electrons (e-) into digital counts, or
Analog-Digital Units (ADUs). Gain is expressed as the number of electrons that
get converted into a digital number, or electrons per ADU (e-/ADU).
Read Noise: Read Noise is the most important reference to measure the
performance of a camera. Lower read noise usually means better SNR and better
quality of image. Read Noise is created within the camera electronics during
the readout process as the electrons are subjected to the analog to digital
conversion, amplification and processing steps that enable an image to be
produced.
Full Well: The electrons are held in each pixel and are converted into
electrical charge which can be measured to show the amount of light that has
fallen on each pixel. The maximum electrical charge possible is termed “full
well capacity”. Under the same conditions such as noise and A/D converter
quality, the greater full well capacity a sensor has, the wider dynamic range
the sensor has. As there is a limit to the depth to which pixels can be made,
the full well capacity is often proportional to the frontal area of the light
gathering element of the pixel.
Dynamic Range is the ratio between the maximum output signal level and the
noise floor at minimum signal amplification (noise floor which is the RMS
(root mean square) noise level in a black image). The noise floor of the
camera contains sensor readout noise, camera processing noise and the dark
current shot noise. Dynamic range represents the camera’s ability to
display/reproduce the brightest and darkest portions of the image and how many
variations in between. This is technically intra-scene dynamic range. Within
one image there may be a portion that is in complete black and a portion that
is completely saturated.
For the SkyEye series camera, the Gain Value is in xxx% mode. Here xxx is used
as the x axis (Gain Value) for the description of the camera performance
??? ????(??) = 20 ∗ ???10[???(???? ?????)/100] ???(???? ?????) = 100 × 10(???
????(??)/20
SkyEye62AC has a significantly low read noise: 0.9 – 1.72 e- (Low Noise Mode).
It is more impressive that this camera comes with low noise mode, which means
users could get even lower readout noise by selecting low noise mode while the
frame rate only drops a little as sacrifice.

- Full resolution
- RAW 16 Bit mode
- Temperature: -5℃

Camera Tilt Adjustment
SkyEye62AC has the tilt adjustment ability. There are 3 sets of screws that
can be used to tilt the sensor, making it parallel with the telescope, two
screws per set for screw in /out.
One can refer to below:
Table 10 Camera Tilt Adjustment
Steps | Operations |
---|
1
| Take a starred image with the camera, user can easily find out the tilt part
in the image through the software(such as siril、ccdinspector、astap), and then
adjust one or more sets of flange adjustment screws on the camera
corresponding to the imaging result.
2| Take another image after the sensor tilt adjustment, and compare it with
the previous one in the software. If the tilt issue is reduced, that means the
adjustment is correct. Otherwise, the adjustment is wrong.
3| Repeat step 2 until the stars in all corners are perfect.
Camera Electric Connection
with Accessories
On the back side of SkyEye62AC, there are 3 connection ports: DC 12V/3A power
port, USB3.0/ USB2.0 port and USB-HUB.
Due to the significantly larger power consumption of IMX571, SkyEye62AC
(including the cooling system) is now booted up only by 12V/3A power supply.
USB3.0 no longer works as a power source but only as a data communication
method. The USB-HUB provides connection with other devices, which allows user
to avoid the mess of cable management. Once another device is connected
through the USB-HUB, it will be connected to PC device through the
USB3.0/USB2.0 port.
