Rolling shutters switch "on" and "off" by clearing the charge that is already within one row and measuring any new incident photons. This allows for an overlap between the acquisition of the current pixel row of a frame (which is acquiring an image), and the lower pixel rows of the previous frame (of an image being readout) (Figure 2).

The primary mechanism of a magnifying glass involves convex or Fresnel lenses. Convex lenses focus light to a point, creating an enlarged virtual image of an object placed within the focal length. Fresnel lenses, on the other hand, offer a thinner, lightweight alternative, albeit with some compromise in image quality due to diffraction.

Some sCMOS sensors can be used in a pseudo-global shutter mode for zero distortion and applications involving hardware changes between frames, such as sequential dual-channel acquisition. This pseudo-global shutter takes advantage of controlling the triggering of the light source. To create this global shutter the camera needs to activate the rolling shutter in dark conditions. Then by triggering the light source and stopping the light at the same time as stopping the camera an area of the array can be illuminated simultaneously, just as a global shutter (as shown in Figure 3).

Some early sCMOS sensors had issues with background quality and noise, limiting the use of CMOS for more demanding applications. To overcome this, higher sensitivity was required to improve the technology. In 2016, back-illuminated sCMOS was created, offering a peak quantum efficiency (QE) of 95% without compromising pixel size, while also improvements were made to background quality. Figure 4 shows a diagram of back-illuminated sCMOS technology, alongside a QE curve indicating the difference between early sCMOS and back-illuminated sCMOS.

CMOS sensor technology differs from CCD sensors as instead of having all sensor pixels fed through one output node, one amplifier and one analog-to-digital converter (ADC) as with a CCD sensor, CMOS sensors work in parallel by having a miniaturized capacitor and amplifier on every pixel, and an ADC for every column (as shown in Figure 1). Each ADC acts simultaneously, reading out entire columns rather than individual pixels of the whole sensor. This makes the process much faster and requires 100x less power than CCD sensor architecture.

The differences in CCD and sCMOS sensor architecture provide both advantages and disadvantages. Some of the advantages of sCMOS technology over CCD technology are as follows:

■ Characteristics ･ Case with excellent strength and airtightness ･ Case material: Glass fiber processing enhancement plastic

sCMOS sensors differ from CCD sensors as they typically have a rolling shutter. Image acquisition begins at the top of the sensor and works its way down, row by row. This allows the sensor to acquire images at much higher framerates with much lower read noise. The speed of an sCMOS camera directly relates to the number of rows, and the row time (i.e. the time between acquisition of one row and another).

Figure 1: Readout architectures comparing interline transfer CCD and sCMOS sensor. Left: Interline transfer CCD format,in which electrons are shifted off the sensor onto a readout register, output node, amplified (by a capacity (C) and anamplifier (A)) and converted into digital grey levels by an ADC. This is then sent to the computer. Right: Typical CMOSformat, where every pixel has a capacitor and amplifier associated. This means that photons that hit each pixel produceelectrons, which are converted to readable voltage on the pixel. Voltages from the whole column are sent to an ADC (in which there is one per column), and these are sent straight to the computer. This makes CMOS cameras much faster as they work in parallel.

Figure 3: The three main shutter formats. Most CCD/EMCCs have a true global shutter with readout from allpixels simultaneously as they are exposed to light. Most sCMOS sensors have a rolling shutter, whichalthough is fast and has high sensitivity (from back-illuminated sensors) can provide artifacts. Pseudo-global shutters use a trigger to control the light source allowing for a global shutter within the rolling shutter iftimes precisely.

Complementary metal-oxide-semiconductor (CMOS) sensors are a technology that has been around since the 1990s. Early CMOS cameras were competing with the more mature CCD technology, but over the 1990s and early 2000s CMOS sensor technology improved to the point where CCD technology was overtaken to become the sensor of choice for consumer digital cameras. This technology was then improved further still to fulfil the higher requirements essential for scientific imaging.
