Laser Marking on Metals: Techniques and Parameters
Laser marking of metals is becoming an increasingly important process in product identification and branding. On our blog, we have previously written about the basic principles of laser marking, the proper ...
Laser Tissue Interactions: Biological Factors to Consider for Dermatology
In 1963, Leon Goldman became the first person to report using lasers in dermatology. Goldman reported the effects of Ruby laser in the selective destruction of cutaneous pigmented structures, like black ...
A Novel Handheld Viscosity Sensor for Medical and Industrial Applications
A research team at Keio University in Japan devised a novel handheld viscosity sensor capable of quick, non-contact in situ measurements. Viscosity is a fundamental property for liquid analysis in a wide ...
Visual SLAM: Sensor Application in Autonomous Mobile Robots
Visual SLAM is now a trending approach in autonomous mobile robot development. Mobile robot is the one capable of transporting itself from place to place. For example, the first mobile robot emerged as a ...
Optogenetics: The Future of Lasers in Neurology for Brain Studies
Optogenetics is the emerging field of using light to control and study neuronal activity. In 2005, a Stanford University team was able to use a light-sensitive microbial protein to control the timing of ...
A Practical and Low-Cost Approach to Artificial Compound Eyes
Compound eyes provide insects with the ability to quickly react to danger. These eyes posses a much wider field-of-view, higher light sensitivity, and superior sensitivity to motion when compared to the ...
Mode-Locked Lasers Improved With Graphene Technology
Ever since graphene sheets were isolated from bulk graphite in 2004, two-dimensional materials have received an immense amount of interest for their unexpected and novel electronic and optical properties. ...
Dental Caries Diagnosis Using Fluorescence Imaging Techniques
A research team from the Military Technical College and from Cairo University in Cairo, Egypt have developed a fluorescence hyper-spectral imaging system which can be employed for diagnosis and detection ...
Photocoagulation Using Lasers for Treating Diabetic Retinopathy
Lasers came into the field of ophthalmology in 1961, when Ruby laser was used to create ocular lesions in rabbits. Unfortunately, creating vascular lesions in the human retina was not effective at that ...
Transmyocardial Surgery: Using Lasers to Increase Vascular Flow
Cardiovascular diseases are among the top causes of death and morbidity in developed nations. In particular, diseases of the coronary arteries are most prevalent. Lasers are well suited to diagnose and ...
