Conversion from light to numerical signal in a digital camera pipeline

Dispersion of a Laser Pulse at Propagation Through an Image Acquisition System

“…its back working distance is 23  0.18 mm. The visual band optical system has  60 field of view (FOV), f/number 2.5 (Toadere, 2010). In figure 7 we have the cross section of a pixel and we can see that it is part of a periodic structure of pixels.…”

“…In spite of the small pixel size capability and a large fill factor, they suffer from low sensitivity and high noise due to the large column's capacitance with respect to the pixel's one. Also during the signal propagation trough the bit configuration it suffers of temporal noises perturbations (Holst & Lomheim 2007), (Toadere & Mastorakis, 2010), (Toadere, 2010). The pixel photodiode works by direct integration of the photocurrent and dark current on the photodiode condenser during the integration time.…”

“…In addition we have the reset, read and FPN noises due to other components electronics. Noises represent an additive process (Toadere, 2010). Shot Noise is associated with the random arrival of photons at any detector.…”

“…The optical fiber is analyzed from the spatial resolution point of view (Toadere & Mastorakis, 2009, 2010. The PSF characterize the image analyses in space but also we can characterize the image in frequency using the optical transfer function (OTF) (Yzuka, 2008).…”

“…The maximum amount of charge that can be accumulated on a photodiode capacitance is called full-well capacity. The initial and maximum voltages are reset V and max V , they depend on the photodiode structures and operating conditions (Holst & Lomheim, 2007), (Toadere, 2010 is the offset FPN due to dark current variation, commonly referred to as DSNU (dark signal non-uniformity).…”
