Infrared detection system with wide-angle infrared thermal imaging lens

Abstract

The invention discloses an infrared detection system with a wide-angle infrared thermal imaging lens, which belongs to the technical field of infrared thermal imaging and comprises a wide-angle thermal infrared imager with the wide-angle infrared thermal imaging lens and a diagnosis bed body for patients to lie on flat, wherein the wide-angle infrared thermal imaging lens of the wide-angle thermal infrared imager is arranged over the diagnosis bed body, and the wide-angle thermal infrared imager and the diagnosis bed body can slide relatively and horizontally. The infrared detection of different types of patients is facilitated, and the accuracy of infrared imaging is improved with the adoption of the thermal infrared imager for the short-distance infrared imaging and the flat-lying infrared detection. In addition, with the adoption of the wide-angle infrared thermal imaging lens, half-body imaging just needs 1.5m; as an imaging distance is shortened, a thermal transmission loss is reduced greatly, and thermal imaging signals are intensified; compared with the traditional thermal infrared imager, the imaging quality is improved by more than 9 times, the system is easy to popularize, the required operating space is small, the imaging environment is easy to control, and the system is easy to popularize and implement and low in cost.

Description

technical field [0001] The invention belongs to the technical field of infrared thermal imaging, and in particular relates to an infrared detection system with a wide-angle infrared thermal imaging lens. Background technique [0002] Infrared thermal imaging technology has been applied to the medical field for more than 40 years. Since British doctor Lawson used infrared thermal imaging technology to diagnose breast cancer in 1956, medical infrared thermal imaging technology has gradually attracted people's attention. In recent years, with the development of photoelectric technology, computer multimedia technology, especially semiconductor technology, the resolution and definition of thermal imaging cameras have reached the level of clinical needs. Therefore, the application of medical infrared thermal imaging cameras has gradually received widespread attention. , has become a new research hotspot in the world. [0003] The half-body imaging distance of the current medical ...

AI Technical Summary

Problems solved by technology

However, when a female patient stands for detection, the breast will be partially compressed, resulting in inaccurate infrared thermal imaging, which may lead to misdiagnosis of lesions and delay diagnosis

[0006] In addition, the current infrared thermal imaging background has not been standardized, and the specific problems are as follows: a. Because the imaging background temperature is not uniform, it has not been standardized, and its images are not objective, such as body temperature 37 ℃, background 35 ℃, or body temperature 37 ℃ ℃, background 25 ℃, it is impossible to compare; b. The uniformity of the background temperature is not enough, it cannot be standardized, and it cannot be compared correctly; c. Lateral airflow will affect the accuracy of the image; d. There is no blackbody correction at any time, so the infrared thermal imager itself There is still drift error in the measured temperature value; e. The camera angle is not standard, it is inconvenient for the patient to rotate, and the results cannot be compared correctly
