Optical Housing Light Control for Thermal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical apparatuses experience thermal instability due to changes in the time ratio of light emission and non-light emission, leading to unstable temperature conditions when the power of incident light changes.
Innovation Solution
An optical apparatus with a control unit that adjusts incident light power to maintain energy equality before and after changes, such as by increasing power during light resumption or using additional light sources to compensate for light stops, ensuring thermal stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If light emission and non-light emission are repeated with constant time ratio, then a quasi-stationary state can be obtained and temperature can be stabilized, but when the time ratio changes, thermal stability deteriorates
Solution Approach 1:
The control unit calculates integrated energy before and after power changes, and adjusts the light emission parameters (duration, intensity) to maintain energy equality, creating a feedback mechanism that compensates for time ratio changes and maintains thermal stability
Solution Approach 2:
The system changes light emission parameters (power, duration, intensity) dynamically to compensate for changes in the time ratio of light emission and non-light emission, maintaining energy balance and thermal stability despite varying operational conditions
2Use of energy by moving object
If power of incident light is increased to compensate for stop time, then energy balance is maintained, but device complexity increases due to control mechanisms
Solution Approach 1:
The control unit automatically calculates and adjusts light emission parameters based on stop/resumption patterns, making the system self-regulating for energy balance without requiring external intervention or complex manual control mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The control unit maintains consistent thermal stability by equalizing energy input, thereby stabilizing the optical apparatus's temperature despite changes in light emission patterns.
Implementation Method 1
energy calculated by integrating the power after the change over a predetermined time becomes equal to energy calculated by integrating the power before the change over the predetermined time
Implementation Method 2
an additional light source different from the light source and configured to generate additional light to be added to the power of the incident light

AI summary
An optical apparatus and an examination apparatus that are capable of improving thermal stability are provided. An optical apparatus according to the present disclosure includes a housing that includes an optical member and on which light is incident, and a control unit configured to control, in a case in which power of incident light incident on the housing changes, the incident light after the change so that energy calculated by integrating the power after the change over a predetermined time becomes equal to energy calculated by integrating the power before the change over the predetermined time. The case in which the power of the incident light changes may include stop and resumption of incidence of the incident light.
