Amblyopia. Anisometropia is a condition in which a person's eyes have substantially differing refractive power. [1] Generally, a difference in power of one diopter (1D) is the threshold for diagnosis of the condition . [2] [3] Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye ...
Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. [1] It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
The device being tested is electrically stimulated and the device output is monitored. This technique is applied to the back side of the semiconductor device, thereby allowing direct access of the laser to the device active diffusion regions. The effect of the laser on the active transistor region is to generate a localized photocurrent. This ...
A molded interconnect device (MID) is an injection-molded thermoplastic part with integrated electronic circuit traces. The use of high temperature thermoplastics and their structured metallization opens a new dimension of circuit carrier design to the electronics industry. [1] This technology combines plastic substrate /housing with circuitry ...

Experimental production of nanopowders.
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
An organic laser is a laser which uses an organic (carbon based) material as the gain medium. The first organic laser was the liquid dye laser. [1] [2] These lasers use laser dye solutions as their gain media. Organic lasers are inherently tunable and when configured as optimized multiple-prism grating laser oscillators can yield efficient ...
