Aims Two imaging systems have been tested, including an advanced X-ray imaging system that utilizes geometric magnification and a mobile phone imaging system. The aim of this experiment is to use resolution phantoms to determine system parameters including resolution, effective pixel sizes, magnification and other geometric parameters. Results X-ray Imaging Image set Mag. Spot size (hxw;um) Effective Px Size (um) Actual Mag. Source/Sample Distance (m) Vertical resolution Horizontal resolution

Kevin Chapman ARTH 2720-001 Term Paper December 5, 2012 Manet and The Bar Edouard Manet’s painting A Bar at the Folies-Bergere, was completed in 1882 and is considered his last great painting. He displayed it at the Paris Salon just one year before his passing. This painting as vexed art historians throughout the years for its complex visual subject matter and leaves Manets true interpretation of his painting in the air for discussion. Although there are many interpretations, A Bar at the Folies-Bergere

Sound is a mechanical wave, propagating through a medium in order for it to travel (Venables 2011a). Ultrasound is defined as high frequency sound waves, above the audible range i.e. >20 kHz (Zidan et al. 2011). These waves are formed using the pulse-echo principle (Venables 2011a). This principle refers to the piezoelectric crystals which are situated in the transducer. When an alternating electrical voltage is applied across the transducer element (Lieu 2010), the element undergoes a series of

Hi! In this discussion, we’ll look at how a DSLR camera works and how the light travels inside a DSLR camera. First, we’ll look at the cross-sectional view of a DSLR camera. That means if you take a camera and cut it open through the center and look at it from the side this is how it looks like. And it’s called the side cross-sectional view. Now let’s see what are the elements that are inside the camera. These are the lens elements. Those are the glass pieces inside the lens. These are just representational

Project objective and Excepted Significance: This work aims to demonstrate petahertz optical-field-induced current signal control in electronic nanocircuit utilizing synthesized femtosecond light fields. That promises an increase in the speed of data processing and information encoding on rates that exceed 1 Pbit/sec, million times faster than the current technology. It will likely extend the frontiers of modern electronics and information processing technologies into the PHz realm. This work will

Arduino Uno R3 is a microcontroller board. It has 14 digital input/output pins. 6 analogue inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It is much more user friendly to use. When using an Arduino it simplifies a large amount of work that needs to be done in order to get a running system.The Arduino hardware platform already has the power and reset circuitry setup as well as the circuitry to program and communicate with the micro over USB. The

The rule of thirds is a powerful compositional technique for making photos more interesting and dynamic. It's also perhaps one of the most well known techniques. The rule of thirds states than an image is most pleasing when its subjects or regions are composed along imaginary lines which divide the image into thirds, both vertically and horizontally. It is actually quite amazing that a rule so seemingly mathematical can be applied to something as varied and subjective as a photograph. But it works

1. Eye piece/ ocular lens: An eye piece is a magnifying lens exists to the microscope which assists in enlarging the sample object. 2. Body tube: A body tube is an necessary part of the microscope. It helps to extend the eye piece and connect eye piece to the objective. 3. Arm: Arm is the part which connected with the base of the microscope. It can be easier to carry the microscope. 4. Revolving nose piece: part of the microscope. This can be holding the objective lenses. At the same time

High-index lenses are made from a substance that refracts more light than traditional lenses. This makes the lenses thinner and lighter. The index of a lens is its ability to bend light efficiently. The higher the index, the less lens material is required to bend the same amount of light. So if you have a higher index, you can have a thinner lens. How do High-Index Lenses Differ from Regular Lenses? High index lenses are made of a material that is capable of bending light to a stronger degree than
