vision. In most cases, laser eye surgery is pain-free and is completed within 15 minutes for both eyes. It takes 24 hours to see improvement in vision without eye glasses or contact lenses.…

useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important application of interferometry is in the Laser Interferometer Gravitation wave Observatory(LIGO) which is used to detect gravitational waves predicted by Einstein.1.1 The LIGO interferometer is like the Michelson Interferometer as shown in…

Technology has changed and advanced vastly over time. Through out these three articles a variety of technological advances are displayed. The first article is about how technology for treasure hunters have improved. The second article is how technology for hurricane hunters have improved. The third article is about how technology has advanced for people who explore looking for ancient civilizations. The most advanced technology for researchers today is the ones used for finding ancient…

As our society becomes more technologically advanced, many things advance with it. This includes criminal investigations, which can be aided by infrared spectroscopy. IR spectroscopy deals with the infrared region of the electromagnetic spectrum. This region is light with a longer wavelength and lower frequency than visible light. (Wikipedia) IR Spectroscopy is a method to identify substances based on their absorption of infrared wavelengths. It is a study of how the molecules of substances can…

if I told you that a laser can reach the earth all the way from space? You’d think it’s pretty cool right? Well it just so happens to be completely true! Scientists have created lasers to communicate from basically anywhere, and I’m here to tell you how it works. A laser shoots out a diverging beam that goes through the transmitter lens that creates a “well focused beam”. The well focused beam then goes through the receiver lens into the receiver diode. This is called laser communication. It is…

Laser Weapon Systems (LaWS) MIDN 3/C Sangrones, Joshua Jacksonville University Laser Weapon System In today’s standards, missiles and rockets are common when it comes to nations’ military warships. However, coinciding with the development of more advanced weapon systems, there are also advances in their counter measures. Such defense systems include the United States Navy’s Laser Weapon Systems (LaWS). Its creation allowed a more cost efficient and more effective way of countering enemy…

The Kinect V2 is composed of a time-of-flight continues-wave camera with a resolution of 512*424 pixels (width*height), an RGB camera with a resolution of 1920*1080 pixels (width*height), an array of 4 microphones and some electronics for signal elaboration. The camera is able to acquire images at a maximum frequency of 30 Hz. Sending out invisible structures pulses into the scene whilst measuring the individual traveling time of each point in the pulse (See figure 3.1, page 16). The operating…

of corneal tissue is created using an automated microsurgical device, either a laser or blade. This corneal flap is lifted and folded back (figure 1). Then the excimer laser preprogrammed with the patient's unique eye measurements is centered above the eye. The surgeon checks that the laser is positioned correctly. The patient looks at a special pinpoint light, called a fixation or target light, while the excimer laser sculpts the corneal tissue. Then the surgeon places the flap back into…

Keep batteries stored in LiPo-safe bags. How will you flow between the activities? Start with a whole group safety briefing and watch the Droneology videos all together on the projector. Break into teams to build, then come back together in P2 to talk through flight dynamics and essential terminology. Split to individual computers to take the Lesson 2 Quiz in C1. Come back together to watch the next batch of videos in C2 and end with a review of safety procedures in the DP. What does FPV stand…

Battle House Laser Tag is a stimulating attraction that has surpassed the limits of a kid-friendly only environment and has progressed into a realistic domain filled with buzzing delight. With this intention, maintaining a lifelike appearance is the key factor in the grave one-and-a-half-hour battle of two energetic competing teams. There are three primary rooms that are important throughout the duration of laser tag, the briefing, storage, and battle room. Undoubtedly, among all the rooms,…
