Summary- U/ y4 `( y. D# q4 `
 Time-of-flight camera (ToF camera) is a range imaging camera system that employs time-of-flight techniques to resolve distance between the camera and the subject for each point of the image, by measuring the round trip time of an artificial light signal provided by a laser or an LED. csuchen.de: X7 Z2 M% S7 W/ g7 f. }
Advantages of ToF cameras • Simple and compact compared to other systems; no moving parts inside and the illumination unit is kept just next to the lens. • Long and accurate (even in centimetres) working distance. • Wide application range; depends neither on whether the object has feature point or not nor on the nature of ambient light (strong or weak). • Uses only a little amount of processing power. • Faster than other 3D laser scannings; can operate up to 160 images per second. . p' d.

Since the COVID-19 virus outbreak in December 2019, the disease has spread to almost 100 countries around the globe with the World Health Organization declaring it a public health emergency. The global impacts of the coronavirus disease 2019 (COVID-19) are already starting to be felt, and will significantly affect the Beta-Galactosidase Assay Kits market in 2020. COVID-19 can affect the global economy in three main ways: by directly affecting production and demand, by creating supply chain and market disruption, and by its financial impact on firms and financial markets. The outbreak of COVID-19 has brought effects on many aspects, like flight cancellations; travel bans and quarantines; restaurants closed; all indoor events restricted; over forty countries state of emergency declared; massive slowing of the supply chain; stock market volatility; falling business confidence, growing panic among the population, and uncertainty about future. This report also analyses the impact of Coronavirus COVID-19 on the Time of (ToF) Camera industry. Based on our recent survey, we have several different scenarios about the Time of (ToF) Camera growth rate for 2020. The probable scenario is expected to grow by a -8.4% in 2020 and the revenue will be 3807 in 2020 from US$ 4156 million in 2019.

In 2017, the Time of (ToF) Camera had fewer applications, but with the development of technology, in 2019, Huawei released the P30 series and added ToF lenses for the first time. After that, some high-end machines use ToF cameras. The ToF camera market is very prosperous and will be the mainstream of mobile phone cameras in the future. However, due to the impact of new coronavirus pneumonia in 2020, the global ToF camera market will decline slightly.

According to a QYR survey, the global market size of upstream GaAs epitaxial wafers reached USD 1.1 billion in 2018. GaAs epitaxial wafers use the epitaxial production outsourcing model in the field of RF applications, which are basically monopolized by four companies, namely, British IQE, Taiwan VPEC (New Optoelectronics), Japan's Sumitomo Chemical and Taiwan's IntelliEPI. IQE is the sole supplier of VCSEL epitaxial wafers in iPhone. 2018 year. Figure 9：Global GaAs Epitaxial Wafer Market Size, 2015-2020 (USD Million)

IQE's market share in the global EPI epitaxial wafer market has reached 60%, and its market share corresponding to VCSEL applications has reached 80%. Taiwan's brand-new Optoelectronics is expected to become Apple's second supplier. The company has accumulated 15 years in the field of EPI epitaxial wafers, and has now sent samples of VCSEL epitaxial wafers to Apple. Domestic GaAs epitaxial wafer manufacturers are mainly concentrated in the LED application field. This application field mainly uses IDM production methods, such as Sanan Optoelectronics and Qianzhao Optoelectronics. Figure 10：Competition pattern of global GaAs epitaxial wafer market in 2019
